2 * Dead Letter Queue (DLQ) Processor

4 * Processes failed BullMQ jobs that exhausted all retries:
5 * 1. Reads failed jobs from the queue
6 * 2. Logs each to the `events` table as `job.failed`
7 * 3. Auto-retries once after 1 hour (transient failure recovery)
8 * 4. If still fails: marks as `permanently_failed`, alerts admin
9 * 5. Exposes GET /v1/admin/dlq for admin inspection
10 *
11 * Registered as a BullMQ repeat job (every 15 minutes).

1/**
2 * Tests for JWT RS256 + refresh token rotation (Fix 1 — E4)
3 *
4 * Verifies:
5 * 1. Access tokens are created and verified with RS256
6 * 2. Refresh token rotation issues new token pair and invalidates old
7 * 3. Reuse of a rotated refresh token revokes the entire family (theft detection)
8 * 4. Logout revokes all refresh tokens for a user
9 * 5. Expired tokens are rejected
10 * 6. HS256 fallback works when RS256 keys not available
