ui: voice recorder pulse + TDS styling, wire mic denied error to input bar

- VoiceMessageRecorder recording dot now pulses (reuses pttLivePulse keyframe)
- Added data-voice-recorder / data-voice-rec-dot / data-voice-waveform attributes
  for TDS targeting: green pulsing dot, cyan waveform bars, subtle border in TDS dark
- Wire VoiceMessageRecorder onError to the same input-bar error display used by
  location errors (mic denied, media error surfaces to user instead of silent fail)
