fix(federation/auth-guard): remediate CRIT-1/CRIT-2 + HIGH-1..4 review findings

- CRIT-1: Validate cert subjectUserId against grant.subjectUserId from DB; use authoritative DB value in FederationContext - CRIT-2: Add @Inject(GrantsService) decorator (tsx/esbuild requirement) - HIGH-1: Validate UTF8String TLV tag, length, and bounds in OID parser - HIGH-2: Collapse all 403 wire messages to a generic string to prevent grant enumeration; keep internal logger detail - HIGH-3: Assert federation wire envelope shape in all guard tests - HIGH-4: Regression test for subjectUserId cert/DB mismatch Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

 /**
 * Unit tests for FederationClientService (FED-M3-08).
 *
 * HTTP mocking strategy:
 *   undici MockAgent is used to intercept outbound HTTP requests.  The service
 *   uses `undici.fetch` with a `dispatcher` option, so MockAgent is set as the
 *   global dispatcher and all requests flow through it.
 *
 *   Because the service builds one `undici.Agent` per peer and passes it as
 *   the dispatcher on every fetch call, we cannot intercept at the Agent level
 *   in unit tests without significant refactoring.  Instead, we set the global
 *   dispatcher to a MockAgent and override the service's `doRequest` indirection
 *   by spying on the internal fetch call.
 *
 *   For the cert/key wiring, we use the real `sealClientKey` function from
 *   peer-key.util.ts with a test secret — no stubs.
 *
 * Sealed-key setup:
 *   Each test (or beforeAll) calls `sealClientKey(TEST_PRIVATE_KEY_PEM)` with
 *   BETTER_AUTH_SECRET set to a deterministic test value so that
 *   `unsealClientKey` in the service recovers the original PEM.

 /**
 * FederationClientService — outbound mTLS client for federation requests (FED-M3-08).
 *
 * Dials peer gateways over mTLS using the cert+sealed-key stored in `federation_peers`,
 * invokes federation verbs (list / get / capabilities), and surfaces all failure modes
 * as typed `FederationClientError` instances.
 *
 * ## Error code taxonomy
 *
 * | Code               | When                                                          |
 * | ------------------ | ------------------------------------------------------------- |
 * | PEER_NOT_FOUND     | No row in federation_peers for the given peerId               |
 * | PEER_INACTIVE      | Peer row exists but state !== 'active'                        |
 * | PEER_MISCONFIGURED | Peer row is active but missing endpointUrl or clientKeyPem    |
 * | NETWORK            | undici threw a connection / TLS / timeout error               |
 * | HTTP_{status}      | Peer returned a non-2xx response (e.g. HTTP_403, HTTP_404)    |
 * | FORBIDDEN          | Peer returned 403 (convenience alias alongside HTTP_403)      |
 * | INVALID_RESPONSE   | Response body failed Zod schema validation                    |
 *
 * ## Cache strategy
 *
 * Per-peer `undici.Agent` instances are cached in a `Map<peerId, AgentCacheEntry>` for
 * the lifetime of the service instance.  The cache is keyed on peerId (UUID).
 *
 * Cache invalidation:
 *  - `flushPeer(peerId)` — removes the entry immediately.  M5/M6 MUST call this on
 *    cert rotation or peer revocation events so the next request re-reads the DB and
 *    builds a fresh TLS Agent with the new cert material.
 *  - On cache miss: re-reads the DB, checks state === 'active', rebuilds Agent.
 *
 * Cache does NOT auto-expire.  The service is expected to be a singleton scoped to the
 * NestJS application lifecycle; flushing on revocation/rotation is the only invalidation
 * path by design (avoids redundant DB round-trips on the hot path).

 # fix(db): bootstrap migrations on local-tier gateway startup
 ## Problem
 Fresh `mosaic gateway install` (npm-installed) leaves the gateway DB schema empty:
 ```
 relation "users" does not exist
 ```
 Sign-in 500s, `auth users create` says "Not signed in", `admin/bootstrap setup`
 also fails — every entry point queries `users` before doing anything else.
 ## Scope
 This PR fixes the **local (PGlite) tier** end-to-end. The postgres-tier path
 has additional pre-existing bugs (see "Known issues, out of scope" below) and
 needs a separate change with real Postgres validation.
 ## Root causes addressed (5 stacked bugs on the local-tier path)
 1. **`packages/db/package.json` `files: ["dist"]`** — the `drizzle/` SQL
   migrations folder is excluded from the published tarball. Even if a
   migrate runner existed, it would have nothing to apply.
 2. **`packages/db/src/migrate.ts`** only supports `postgres-js`. Local-tier
   gateways use embedded PGlite, which can't be reached over a postgres wire
   protocol — so `runMigrations()` is unusable for the local tier.
 3. **`apps/gateway/src/database/database.module.ts`** never invokes
   migrations at startup. The module creates the DB handle and storage
   adapter, but no consumer calls `.migrate()` on either. `mosaic storage
 migrate` CLI even claims "pglite runs schema setup automatically on first
   connection via `adapter.migrate()`" — but `adapter.migrate()` is only
   called by tests, never at runtime.
 4. **`createPgliteDb` does not load the pgvector extension.** Migration 0001
   declares `CREATE EXTENSION IF NOT EXISTS vector;` for the
   `insights.embedding` column. Bare PGlite has no pgvector — the migration
   fails on extension control file lookup.
 5. **Drizzle's PG migrator wraps every migration in one outer transaction.**
   Migration 0009 does `ALTER TYPE grant_status ADD VALUE 'pending'` and then
   `ALTER TABLE federation_grants ALTER COLUMN status SET DEFAULT 'pending'`.
   Postgres' `check_safe_enum_use` rejects the second statement because the
   new enum value isn't committed yet. Splitting the migration into two
   files doesn't help — drizzle batches all migrations into one outer tx.
 ## Fix
 - `packages/db/package.json` — ship `drizzle/` in `files`.
 - `packages/db/src/client-pglite.ts` — load `@electric-sql/pglite/vector`.
 - `packages/db/src/migrate.ts` — add `runPgliteMigrations(handle)`. Walks the
  Drizzle journal and runs each statement-breakpoint chunk through PGlite's
  `client.exec()` (Simple Query protocol → autocommit per statement). Writes
  to the standard `drizzle.__drizzle_migrations` ledger so the result is
  interoperable with `runMigrations()` on a postgres-backed deployment.
  Per-statement try/catch surfaces which statement of which migration failed
  and the ledger row is only written on full success.
 - `packages/db/src/index.ts` — re-export.
 - `apps/gateway/src/database/database.module.ts` — implement `OnModuleInit`:
  - Local tier → `runPgliteMigrations(handle)`, then `storageAdapter.migrate()`
    (the local storage adapter has its own kv tables in a separate PGlite dir).
  - Postgres tier → `storageAdapter.migrate()` only, since
    `PostgresAdapter.migrate()` already calls `runMigrations(url)` against
    the same DATABASE_URL — we deliberately don't double-call.
  NestJS awaits `onModuleInit` before `app.listen()`, so DB-dependent modules
  see a populated schema before any HTTP traffic is accepted.
 - `packages/storage/src/test-utils/pglite-with-vector.ts` — **deleted**.
  The "intentionally not exported" rationale is moot now that migration 0001
  forces pgvector load anyway. `migrate-tier.integration.test.ts` switched
  to `createPgliteDb` + `runPgliteMigrations` from `@mosaicstack/db`.
 ## Tests
 `packages/db/src/migrate.test.ts`:
 - Verifies `runPgliteMigrations` creates the BetterAuth tables (the original
  failure mode).
 - Idempotence (transitively re-runs migration 0009).
 - Partial-failure: pre-creates a conflicting `users` table, asserts the
  thrown error includes statement context (`hash=… statement #N failed`)
  and that no ledger row was written.
 ## QA evidence
 End-to-end on a fresh PGlite install:
 - `[DatabaseModule] Applying PGlite schema migrations...` then
  `Initializing storage adapter (pglite)...` in startup log.
 - `GET /api/bootstrap/status` → `{"needsSetup":true}` HTTP 200 (was 500
  with `relation "users" does not exist`).
 - `POST /api/bootstrap/setup` with empty body → HTTP 400 with Zod
  validation error (was 500), confirming the request reached the
  validator past the table-existence check.
 ## Known issues, out of scope (file separately)
 - **Postgres-tier first install is still broken.** `runMigrations()` uses
  Drizzle's `migratePostgres`, which has the same outer-transaction problem
  as PGlite's migrator. A fresh standalone-tier install would also fail at
  migration 0009. Inline TODO in `migrate.ts:31-35` flags this. Fixing it
  needs either (a) a shared per-statement loop reused for both drivers, or
  (b) splitting migration 0009.
 - **`drizzle/meta/_journal.json` has 0009 ordered before 0008** (`when`
  values `1745280000000` < `1776822435828`). `migratePostgres` skips by
  `created_at < folderMillis`, so on a postgres deployment that already
  applied 0008, 0009 would be skipped forever. Our hash-based skip in the
  PGlite path sidesteps this.
 - **No advisory lock around the migration loop.** Two gateway processes
  pointed at the same DATABASE_URL would race. PGlite is single-process by
  file lock so the local tier is fine; postgres-tier deployments should add
  `pg_advisory_lock(<deterministic-id>)` around the loop in a follow-up.
 - **`mosaic storage migrate` CLI message is misleading** — it claims
  "automatic on first connection via adapter.migrate()" but the adapter
  doesn't self-migrate. With this PR the gateway invokes it explicitly, but
  the CLI message could still be tightened.
 - **Crash mid-migration leaves a partial-state PGlite DB without a ledger
  row.** Detected loudly on next boot (the replay errors on "already
  exists"), but recovery is manual (drop the partially-applied objects or
  insert the migration hash into `drizzle.__drizzle_migrations`). A robust
  fix would add a "started_at" column to a sidecar table to detect
