fix: update coordinator-api module path and add ML dependencies

Coordinator API Module Path Update - Complete:
✅ SERVICE FILE UPDATED: Changed uvicorn module path to app.main
- systemd/aitbc-coordinator-api.service: Updated from `main:app` to `app.main:app`
- WorkingDirectory: Changed from src/app to src for proper module resolution
- Reason: Correct Python module path for coordinator API service

✅ PYTHON PATH CONFIGURATION:
🔧 sys.path Security: Added crypto and sdk paths to locked paths
