CRIT-1: Replace nonexistent x-admin-key header with Authorization: Bearer <token>;
add bootstrapAdmin() to call POST /api/bootstrap/setup on each pristine gateway
before any admin-guarded endpoint is used.
CRIT-2: Fix cross-gateway peer FK violation — peer keypair is now created on
Server B first (so the grant FK resolves against B's own federation_peers table),
then Server A creates its own keypair and redeems the enrollment token at B.
HIGH-3: waitForStack() now polls both gateways in parallel via Promise.all, each
with an independent deadline, so a slow gateway-a cannot starve gateway-b's budget.
MED-4: seed() throws immediately with a clear error if scenario !== 'all';
per-variant narrowing deferred to M3-11 with explicit JSDoc note.
Also: remove ADMIN_API_KEY (no such path in AdminGuard) from compose, replace
with ADMIN_BOOTSTRAP_PASSWORD; add BETTER_AUTH_URL production-code limitation
as a TODO in the README.
