feat: Phase 2 — missed call queue ingestion, auto-assignment, endpoints

- MissedQueueService: polls Ozonetel abandonCalls every 30s, dedup by phone
- Auto-assigns oldest PENDING_CALLBACK call on agent Ready (dispose + state change)
- GET /api/worklist/missed-queue, PATCH /api/worklist/missed-queue/:id/status
- Worklist query updated with callback fields and FIFO ordering
- PlatformGraphqlService.query() made public for server-to-server ops
- forwardRef circular dependency resolution between WorklistModule and OzonetelAgentModule
