fix(gateway): serialize bootstrap setup with an advisory lock (#1430)

POST /api/bootstrap/setup checked the zero-user count and then created the
first admin with nothing making the two atomic, so two concurrent setup
requests could both pass the check and each create an admin user plus an
admin API token.

Setup now runs inside a db.transaction that first takes
pg_advisory_xact_lock(BOOTSTRAP_SETUP_LOCK_KEY): the second concurrent
caller blocks until the first commits, re-reads the count, and gets 403.
The lock is transaction-scoped, so it also serializes across gateway
replicas sharing the database.

Spec: mock db gained transaction/execute; new assertions pin
lock-before-count ordering, and a new suite pins 403 + no createUser call
when users already exist.

Closes #1430

-# RBAC Grant Model Contract
-
-Status: DRAFT — awaiting ratification (webui-audit S2, contract 2 of 9).
-Authority: PRD Part I §4 ("Granular RBAC: admins restrict access per company,
-estate, and project; grants are evaluated down the chain") and the
-native-kanban SOT Amendment A1 (§8.1.3 RBAC evaluation, §8.3 acceptance 2).
-This document defines the grant vocabulary, evaluation semantics, and
-revocation propagation that the hierarchy schema contract
-(`docs/requirements/hierarchy-schema.md`, contract 1) attaches to. Contract 1
-pins the `hierarchy_grants` table shape and defers the `role` vocabulary and
-the meaning of "authority" here; the identity contract
-(`docs/requirements/identity-lifecycle.md` §1.4) pins that account creation
-grants nothing.
-
-Revision 2 (independent review, GLM 5.3): §1.1 consequence analysis
-completed — the two existing platform-admin bypass code paths are named as
-non-conformant and §7.4 retires them; team grant subjects suspended pending
-a team contract (§1.4, §3.3–3.4, §7.5); no-self-escalation restated with
-its true rationale and a constructible observable (§4.2, §7.7);
-node-creation seeding scoped to the bootstrap path, resolving the §7.7/§4.3
-contradiction; A1 quotation corrected; audit-field provenance corrected;
-principal-position consequence named (§1.3); membership-row,
-fail-closed-fault, and existence-oracle observables added (§7);
-role-string namespacing rule added (§4.5); ruling request now names the
-interpretive resolution of PRD "admins".
-
-Scope: the roles that can appear in `hierarchy_grants.role`, what a grant at
-each hierarchy level confers, how grants evaluate down the chain, how
-revocation propagates, and who may manage grants. Out of scope: the hierarchy
-tables themselves (contract 1), workspace-internal membership and its
-role/capability vocabulary (native-kanban SOT REQ-ID-001 and its implementing
-schema), roll-up projection semantics (contract 8), wizard seeding
-(contract 3), the team model (suspended here; see §1.4).
-
-## 1. Three authority layers, none substitutable
-
-1. **Platform role** (`users.role`, better-auth: `member` | `admin`) governs
-   instance administration — user management, system settings, provider
-   configuration. It is not tenancy authority: holding platform `admin`
-   confers **no implicit hierarchy grant and no workspace authorization**.
-   An operator who should see tenant content holds an explicit, audited
-   grant like anyone else. This is the deny-by-default consequence of A1
-   §8.1.3 ("not a bypass of workspace authorization"). `AdminGuard`'s
-   `role === 'admin'` check on admin endpoints stays the platform role's
-   only meaning. **Two shipped code paths violate this rule today and are
-   implementation defects this contract makes non-conformant:** (a) the
-   command authorization service short-circuits every command scope to
-   allowed for platform admins
-   (`apps/gateway/src/commands/command-authorization.service.ts`,
-   `hasScope` returning true when `role === 'admin'`), and (b) the MCP
-   scope derivation maps platform `admin` to tenant-admin MCP scopes
-   including task create/update
-   (`apps/gateway/src/mcp/mcp.service.ts`,
-   `deriveMcpToolScopesForUser`). Ratifying this contract revokes both;
-   §7.4 names them as the surfaces the deny-by-default test retires.
-2. **Hierarchy grants** (`hierarchy_grants`, contract 1 §3) declare tenancy
-   authority at company, estate, or platform-project scope and evaluate down
-   the chain to workspace-scoped authorization (§3 below).
-3. **Workspace membership** (SOT REQ-ID-001) remains its own mechanism.
-   A chain grant confers command authorization over descendant workspaces;
-   it does not create membership rows, and row-level principal positions
-   (task owner, proposer, decision actor) still require ACTIVE workspace
-   membership exactly as REQ-TEN-001/REQ-ID-001 acceptance states.
-   Consequence, stated so implementing PRs do not weaken REQ-TEN-001 to
-   remove the friction: a chain-granted actor who is not a workspace member
-   may issue the write commands their role implies but cannot occupy a
-   principal position — any command taking a principal argument must name
-   an ACTIVE member of the target workspace (§7.2 enumerates this cell).
-4. **Team grant subjects are suspended.** Contract 1 §3.1 reserves a
-   `team_id` attachment point, but no ratified contract yet defines the
-   team it would bind: the only existing `teams` table is the legacy global
-   Brain table (own authority columns, no workspace binding, not
-   repurposed per contract 1 §1.3), while the SOT's teams are
-   workspace-bound (REQ-ID-001) — and a workspace-bound team holding a
-   company-level grant would be a cross-workspace authority group nothing
-   has ratified. Until a team contract defines the subject (which table,
-   which membership rows, and its relation to D2/REQ-ID-001), creating a
-   grant with a team subject MUST be refused at the command surface (the
-   schema column remains, per contract 1). §3's evaluation semantics for
-   team-conferred grants are specified now so the team contract activates
-   them without amending this one.
-
-## 2. Role vocabulary
-
-One vocabulary at every hierarchy level, totally ordered — a higher role
-includes everything below it:
-
-1. `viewer` — read: sees the node, its subtree structure, and the roll-up
-   aggregates over descendant workspaces (within contract 8's carve-out
-   bounds); read access to descendant workspace content per the SOT's read
-   command families. No mutation of anything.
-2. `member` — work: everything `viewer` has, plus write authorization for
-   business/orchestration command families in descendant workspaces (the
-   concrete command-family mapping is implementation work under SOT
-   REQ-ID-001; this contract pins that `member` maps to the workspace write
-   families and nothing structural).
-3. `owner` — structure: everything `member` has, plus hierarchy mutations on
-   the subtree (create/rename/delete child nodes, transfers per §5), and
-   grant management on the node and its subtree (§4).
-
-No other value is valid in `hierarchy_grants.role`; the column is
-constraint-checked against exactly these three. Extending the vocabulary is a
-contract amendment, not an implementation decision.
-
-## 3. Evaluation semantics
-
-1. **Deny by default.** No grant on any ancestor → no authority. There are
-   no implicit grants: not from platform role (§1.1), not from creating a
-   node (§4.3), not from workspace membership (membership without a chain
-   grant confers exactly what the SOT's own membership rules confer inside
-   that workspace, nothing up the chain).
-2. **Down-the-chain only.** A grant on a node applies to that node and its
-   entire descendant subtree. Nothing evaluates upward or sideways: a grant
-   on an estate says nothing about the parent company or sibling estates.
-3. **Effective role = maximum.** A subject's effective role at any node is
-   the highest role among grants held directly by the subject's user on
-   that node or any ancestor — and, once the team contract activates team
-   subjects (§1.4), grants held by any team the user is a member of on that
-   node or any ancestor. Roles never subtract — there is no negative/deny
-   grant in this model; revocation is deletion (§6).
-4. **Team grants follow live membership** (specified now, active only per
-   §1.4). A team grant confers its role on the team's current members,
-   evaluated at decision time. Leaving the team is loss of the grant with
-   §6's propagation bound.
-5. **Live evaluation, fail closed.** Authorization decisions derive from the
-   live grant and team-membership rows (or from a cache that is invalidated
-   in the same transaction as any grant/membership/hierarchy mutation). A
-   decision path that cannot read grant state denies. No materialized ACL is
-   ever authoritative.
-6. **Tenant context stays derived from authenticated authority**
-   (REQ-TEN-001). The chain adds where grants can be declared; a workspace
-   request is still authorized against that workspace, with the chain
-   contributing the effective role — never letting the chain become what A1
-   §8.1.3 forbids: "a bypass of workspace authorization".
-
-## 4. Grant management
-
-1. Creating, changing, or revoking a grant on a node requires effective
-   `owner` on that node (directly or via any ancestor).
-2. **No self-escalation.** A grant manager cannot create a grant with a role
-   higher than their own effective role on the target node. Under the §2
-   vocabulary this rule is currently implied by §4.1 (managers are `owner`,
-   the top role — no constructible grant exceeds it); it is stated
-   explicitly so it survives any future amendment that decouples
-   grant-management authority from role height. Its observable is the §7.7
-   audit invariant, not a refusal test.
-3. **Bootstrap of authority is explicit; inheritance covers the rest.**
-   Creating the first company (the wizard path, contract 3) and any
-   top-level company creation MUST name the initial `owner` grant in the
-   same audited operation — a top-level node has no ancestor to inherit
-   from, so without this the node would be unownable. Creating a child node
-   (estate, platform-project, workspace) requires effective `owner` on the
-   parent (§2.3) and confers no automatic grant; the creator's authority
-   over the new node already follows from §3.2 down-the-chain evaluation.
-   The creating command MAY additionally name an explicit initial grant for
-   a child node; it is not required to.
-4. Every grant mutation is a semantic audit event under contract 1 §5.2's
-   guarantees, extended by this contract with two further fields: the event
-   carries actor, verb, target, **subject, and role** (subject and role are
-   this contract's addition; contract 1 §5.2 does not enumerate them).
-5. **Role strings are namespaced.** `viewer`/`member` exist at hierarchy
-   level, `member`/`admin` on `users.role`, and the current command layer
-   uses a third `viewer|member|admin` vocabulary — same strings, different
-   meanings. Any serialized role string (audit events per §4.4, API
-   responses, logs) MUST identify its layer (e.g. `hierarchy:owner`,
-   `platform:admin`); a bare role string in a serialized artifact is
-   non-conformant.
-
-## 5. Transfer authority (completes contract 1 §4.2)
-
-"Authority over BOTH the source and the destination parent" means: effective
-`owner` on the current parent node (or an ancestor) AND effective `owner` on
-the destination parent node (or an ancestor), evaluated at transfer time in
-the transfer's own transaction. One subject must hold both; two cooperating
-half-authorized subjects are not a transfer protocol this contract defines.
-
-## 6. Revocation propagation
-
-1. Revoking a grant (deleting the row), removing a user from a team that
-   carries a grant (once team subjects activate, §1.4), or the cascade
-   deletion of a node's grants during node deletion (contract 1 §3.3) all
-   propagate identically: the authority derived from that grant is gone for
-   every descendant workspace.
-2. **Bound:** the next authorization decision on any affected transport
-   decides against the revoked grant. Concretely: no new HTTP/MCP command
-   authorized by the revoked grant after the revoking transaction commits;
-   an open Socket.IO connection whose subscriptions depend on the revoked
-   grant is re-evaluated within 30 seconds or at its next inbound message,
-   whichever comes first (same bound as the identity contract's §7.1
-   deactivation rule; same mechanism may serve both).
-3. Revocation is subtractive only in effect, not in representation: the
-   evaluator never needs tombstones; deletion of the row is the revocation.
-
-## 7. Verification requirements
-
-Binding on the implementing PRs (extends A1 §8.3 acceptance 2–3 and
-contract 1 §6):
-
-1. Vocabulary: the role CHECK constraint rejects any value outside
-   `viewer|member|owner` (real-PostgreSQL witness, `ci-postgres` service in
-   the `test` CI step).
-2. Per-level conferral: for each of the three levels × three roles, a grant
-   yields exactly the implied workspace authorization in a descendant
-   workspace and nothing in a non-descendant workspace (the A1 §8.3
-   "exactly the permissions the chain implies" matrix, enumerated). The
-   matrix includes: a chain grant creates zero workspace-membership rows
-   (assert row counts); a chain-granted non-member is refused as the
-   principal argument of any principal-taking command while their
-   non-principal writes succeed (§1.3); structure reads leak no existence
-   of nodes the reader holds no grant on (no cross-tenant existence
-   oracle, A1 §8.3 acceptance 3).
-3. Ordering: `owner` ⊇ `member` ⊇ `viewer` behaviorally — each higher role
-   passes every lower role's positive cases.
-4. Deny-by-default: platform `admin` with no grant reaches no tenant
-   content — asserted against the two §1.1 non-conformant surfaces after
-   their retirement: the command-authorization admin short-circuit and the
-   MCP tenant-admin scope derivation both gone (a platform admin with no
-   grant is refused workspace commands and receives no tenant MCP scopes);
-   workspace member with no chain grant gains nothing outside SOT
-   membership semantics; fresh account reaches nothing (identity contract
-   §1.4 cross-check).
-5. Team subjects: while suspended (§1.4), creating a team-subject grant is
-   refused at the command surface. On activation by the team contract:
-   user-direct and team-conferred grants combine to the maximum; team-leave
-   drops authority within the §6.2 bound; decision-time evaluation
-   witnessed (grant added → next decision allows; no restart or re-login
-   required).
-6. Revocation: each revocation path in §6.1 denies the next command on
-   every transport; the socket bound is measured; a cached-authorization
-   implementation proves transactional invalidation (grant revoked and
-   decision made on two distinct physical connections). Fail-closed fault
-   witness for §3.5: with grant state unreadable (fault injection), the
-   decision denies.
-7. Grant management: non-`owner` cannot mutate grants; top-level company
-   creation without the named initial `owner` grant is refused, while child
-   node creation under ancestor authority succeeds without one (§4.3 both
-   directions); every mutation produces its audit event with the §4.4
-   fields. Self-escalation observable: over the audit event stream, every
-   grant-create/change event's role is ≤ the acting user's effective role
-   on the target at event time (reconstructable invariant, not a refusal
-   test — see §4.2).
-8. Transfer: both-sides `owner` accepted, each single-side case refused
-   (completing contract 1 §6.5).
-
-## Ruling request
-
-Ratify sections 1–7 as written, with one decision embedded and one
-interpretive resolution named:
-
-- Decision: platform `admin` confers no implicit tenant access — operators
-  see tenant content only through explicit, audited grants (§1.1), which
-  retires the two existing admin bypass paths named there. Say "agreed" or
-  name the implicit access you want platform admins to keep.
-- Interpretive resolution (for visibility, not a separate question): PRD
-  Part I §4 says "admins restrict access per company, estate, and project";
-  this contract resolves "admins" as hierarchy `owner`s (§4.1), not
-  platform admins. A1 §8.1.3 does not attribute grant declaration to
-  platform admins, and the §1.1 decision above is what makes this reading
-  binding.
