 - [x] **M — Add bounded duplicate-generation protection.** Consistent portrait/reference, voice-design, and casting
   jobs now deduplicate repeated requests with bounded, expiring `Idempotency-Key` contracts.
 - [ ] **M — Improve large-table performance.** Character productions and the flat voice library now paginate at 50
