- Add missing _get_auth_token() function that caused NameError in Settings
- Replace _client.auth_username/role/source() calls with _get_auth_*()
helpers (methods don't exist on SiloClient, crashed auth dock widget)
- Fix connect() in silo_origin.py to show login dialog instead of just
revealing the dock panel (was using non-existent Command.get() API)
- Separate toolbar (file ops) from menu (admin/management commands)
- Remove DEBUG logging from Silo_Save command
- Fix long line formatting in silo_origin.py
