refactor: replace unpublishTrack mute with setMicrophoneEnabled (Phase 1 RNNoise prep)

Browse Source 
- syncMic now uses setMicrophoneEnabled(false/true) to mute/unmute the mic
  track in-place instead of tearing down and re-publishing via unpublishTrack().
  This eliminates WebRTC renegotiation on every mute cycle and preserves the
  Web Audio pipeline for future AudioWorklet injection (RNNoise WASM).
- Unify DmCallView mute/deafen with the primary syncMic path — removed direct
  setMicrophoneEnabled calls, added missing auto-mute/unmute on deafen toggle.
- Strip redundant applyConstraints from VoiceControls noise suppression toggle
  that was hardcoding echoCancellation:true/autoGainControl:true and fighting
  AudioManager's constraint pipeline.
