Subject: [PATCH] feat: Push-to-talk on voice FAB button

- Hold FAB to open panel and start recording immediately
- Release to stop recording and send after 1s buffer
- Orange pulsing animation when PTT active
- PTT also works on record button inside modal
- Added stopRecordingAndSend exposed method
