fix(ws/voice): start-Frame-Optionen (Provider, audio_stream, language) ehren

Browse source 
Bug: /ws/voice nutzte bei explizitem {"type":"end"} die Optionen aus dem END-Frame.
voice_loop schickt Provider und audio_stream aber im START-Frame -> diese wurden
komplett ignoriert. Folge: --stt/--llm/--tts-provider und --stream-audio hatten
ueber /ws/voice KEINE Wirkung (Hybrid lief faktisch ueber die Cloud-Defaults,
audio_stream wurde nie aktiv).

Fix: start-Frame als start_options merken und beim Turn mit dem end-Frame mergen
({**start_options, **end}); VAD-Auto-Ende nutzt ebenfalls start_options.

Verifiziert: Provider-Override aus dem START-Frame greift (neuer Test); mit
audio_stream kommen jetzt mehrere Audio-Chunks ~6-7 s VOR dem fertigen Text
(satzweises Vorlesen startet frueher). 65 Tests gruen.
