feat: production ingest test suite with detailed logging

Add comprehensive E2E test scripts and logging for production testing:

- test_prod_ingest_real.sh: Full ingest test against K8s cluster with api-gw
- apply_migrations.sh: Manual database schema migration (backup method)
- collect_prod_logs.sh: Pod log collection before/after tests
- run_production_test.sh: Orchestrates full test + log collection
- tests/integration_ingest_with_gw.rs: Integration test with embeddings
- tests/unit_ingest_logging.rs: Unit tests for extraction pipeline

Enhanced logging in ingest_worker.rs:
- Per-record event tracking (extraction, save)
- Entity and edge operation logging
- Error accumulation and reporting
- Structured logging for observability

Production testing identified root cause:
- Ingest + embedding pipeline working correctly
- Entity extraction functional
- Database schema missing (migration not applied)
- Logs clearly show: relation "memory_entity" does not exist

Next: Trigger DB Migration workflow in Forgejo Actions to apply
crates/mem-store/migrations/*.sql files.
