daemon: fix control-panel server crash in the windowed frozen exe

Browse Source 
The onefile build is windowed (no console), so sys.stderr is None and uvicorn's
default logging dictConfig fails with "Unable to configure formatter 'default'",
which took the whole settings-panel server down (the BLE side kept working, but
the Settings window couldn't load). Pass log_config=None so uvicorn skips its own
logging setup — the daemon has its own file logger and doesn't need uvicorn's.
