serve.py lived only on workpc, which was fine while systemd launched it and is
not fine now that mavgpud does. Two endpoints and no framework: /health answers
503 until the model is loaded, /transcribe takes raw PCM and returns
{"text","confidence"}.
The unit carries CW2_TOKEN through EnvironmentFile and the child inherits it,
so the token is never a flag value.
