fix(security): harden auth and status-list allocation

[sign-mark]

What changed

• Restrict JWT issuer and JWKS resolution to trusted issuers configured through JWT_TRUSTED_ISSUERS or the Keycloak realm.
• Require JWT authentication for passkey management and enforce authenticated-user ownership for reads, updates, and deletes.
• Serialize status-list allocation and add database constraints/migration to prevent duplicate allocation under concurrency.

Why

The previous behavior trusted an unverified JWT issuer while selecting JWKS, allowed passkey operations without consistent caller ownership checks, and relied on application-level coordination for status-list uniqueness.

Impact

Deployments can optionally configure a comma-separated JWT_TRUSTED_ISSUERS allowlist. When omitted, the configured Keycloak domain and realm are used. The included migration adds uniqueness safeguards for issued credential slots and active issuer allocations.

Validation

• Targeted issuer, passkey, and status-list allocation unit tests: 4 suites, 12 assertions.
• Relevant services compiled successfully.
• Prisma schema, ESLint, and whitespace/diff checks passed.

Fixes #1705

Summary by CodeRabbit

• New Features

  • Added configurable JWT trusted-issuer validation and secure JWKS resolution.
  • Added authenticated ownership checks and actor tracking for passkey operations.
  • Improved passkey credential normalization and status-list allocation safeguards.
  • Added stronger credential-slot uniqueness protections.

• Bug Fixes

  • Prevented unauthorized access to other users’ passkeys.
  • Improved handling of concurrent and exhausted status-list allocations.
  • Preserved allocations when credential offers are successfully created.
  • Rejected invalid or unsafe JWT issuer configurations.

• Tests

  • Expanded coverage for JWT security, passkey ownership, and status-list allocation.

Thanks for tackling this — all three fixes are aimed at real issues. The issuer allowlist closes a genuine bypass (the old strategy built the JWKS URL straight from the token's iss and swallowed JWKS errors), the passkey ownership checks close an IDOR on delete/rename, and the advisory lock + unique index should hold up across replicas. Tests pass locally (4 suites / 19 tests), lint clean.

One thing below looks like it'll break first-time device setup — worth sorting before merge. Three small nits for the road:

• [nit] new URL() in validateIssuer throws a bare TypeError instead of your friendly "Invalid trusted JWT issuer" message
• [nit] trailing slashes are trimmed for the JWKS lookup but jsonwebtoken's issuer check compares raw, so a token with a trailing-slash iss passes one gate and fails the other
• [nit] if allocatedCount ever drifts from the bitmap, the catch path surfaces a 500 ("Status list bitmap is full") instead of rolling a fresh list

Detect collisions with existing credentialId values.

The preflight groups only normalized values from devices. It does not compare them with non-null credentialId values already stored on other rows.

For example, a current row can contain credentialId = 'abc' while a legacy row contains devices.credentialID = 'abc'. The preflight passes, but the update fails on the unique constraint.

Include existing column values in the collision candidate set. Count distinct row IDs so that a row with matching JSON and column values does not report itself as a collision.
