Christian Gick fa9e95b250 fix(noise): filter STT noise annotations via on_user_turn_completed ...

Replace broken _VoiceAgent stt_node override with _NoiseFilterAgent that uses
on_user_turn_completed() + StopResponse. This operates downstream of VAD+STT
so no backpressure risk to the audio pipeline.

When ElevenLabs scribe_v2_realtime produces *Störgeräusche* etc., the agent
now silently suppresses them before the LLM responds. The prompt-based filter
is kept as defense-in-depth.

Fixes: MAT-41
