57577b42c9 Fix Android audio routing - use music stream for speaker output
- Changed audioStreamType from 'voiceCall' to 'music' on Android
  - voiceCall stream defaults to earpiece
  - music stream defaults to speaker
- Added Debug tab to test voice calls with detailed logs
- Added speaker/earpiece toggle button with proper stream switching
- Full Android AudioSession support for LiveKit voice calls

audioSession.ts:
- configureAudioForVoiceCall: uses music/media for speaker output
- setAudioOutput: switches between music (speaker) and voiceCall (earpiece)
- reconfigureAudioForPlayback: ensures speaker output on Android

debug.tsx:
- Added platform info display
- Added speaker toggle with logging
- Improved UI with control rows
