fix: adapt ingest_worker to production DB schema
- Match memory_entity columns: id, project_id, name, entity_type, description, t_created, t_updated, confidence
- Match memory_edge columns: id, project_id, source_entity_id, target_entity_id, relation_type, fact, t_valid, t_invalid, t_created, confidence
- Convert OffsetDateTime to RFC3339 strings for TIMESTAMPTZ binding
- E2E test confirms: entities save successfully to production DB
Entities extraction working. Next: fact extraction and edges, query handler.
