Phase 6 complete: Edge metrics endpoints

Edge API:
- Implemented metrics service to record and retrieve edge metrics
- Implemented metrics router endpoints (record, list, get, delete)
- Fixed datetime timezone issues for PostgreSQL compatibility
- Updated EdgeMetrics schema to match service implementation
- Dropped and recreated edge_metrics table to fix schema mismatch

Working endpoints:
- POST /v1/metrics/ - Record metrics
- GET /v1/metrics/ - List metrics
- GET /v1/metrics/{metric_id} - Get metric details
- DELETE /v1/metrics/{metric_id} - Delete metric

All Edge API phases (1-6) now complete
