feat: voice_preload/voice_ready — Feedback wenn neue Stimme geladen ist

XTTS-Bridge:
  - empfaengt neuen voice_preload Type, rendert stumm "ja." fuer die Stimme
    via TTS-Queue (damit kein Konflikt mit echtem TTS)
  - horcht zusaetzlich auf config-Broadcasts: wenn Diagnostic global die
    Stimme wechselt, wird auto-preloaded
  - broadcastet voice_ready mit Dauer (loadMs) oder error

RVS: voice_preload + voice_ready zur ALLOWED_TYPES-Liste.

App (SettingsScreen): beim Wechsel senden wir voice_preload, zeigen einen
Spinner in der Voice-Row und einen Toast mit "Stimme X bereit (Ns)".
App (ChatScreen): Toast auch hier — falls User gerade nicht in Settings ist.

Diagnostic (server+UI): voice_ready wird an Browser durchgereicht, ein
Status-Text unter dem Voice-Dropdown zeigt "wird geladen" → "bereit".
