feat(tts): Chatterbox-Provider (hohe Qualitaet + Voice-Cloning) anbinden

Browse source 
Loest #7. Der chatterbox-Stub wird durch eine echte Anbindung an den lokalen
Chatterbox-HTTP-Dienst ersetzt (POST /speak -> /status pollen -> GET /audio, WAV).
no_playback=true -> der Dienst spielt nicht lokal ab, liefert nur Bytes. WAV->PCM
(24 kHz, Resampling bei Bedarf). Waehlbar via tts_provider=chatterbox; piper bleibt
der schnelle Default (chatterbox ist ~echtzeit-langsam, dafuer klonbare Stimme).

- config: CHATTERBOX_BASE_URL/_VOICE/_LANG/_SPEED/_TIMEOUT; Registry verdrahtet
- Tests: gemockter httpx (Synthese, WAV/Resample, Job-Fehler, Stimmenwahl)
- Doku: README, Architektur (#7), deploy/README (GPU-Pinning per UUID, no_playback)
