* feat(voice): unified mobile voice bar with gesture-isolated PTT row
Replace separate VoiceStatusChip + VoicePttButton with a single
CompactVoiceBar widget that combines both into a two-row layout:
- Control row (tap): status text, mute, deafen, settings chevron
- PTT row (hold): full-width hold-to-talk, shown only in PTT mode
Gesture isolation prevents mis-touch between rows: the control row
uses tap-only InkWell/IconButton while the PTT row uses a raw
Listener for pointer-down/up events.
Key changes:
- Add CompactVoiceBar widget with state-colored container (normal,
muted, talk-power-blocked)
- Remove mute/deafen IconButtons from AppBar headerActions
- Restructure voice details sheet into primary section + collapsible
ExpansionTiles (audio processing, PTT capability, debug)
- Optimistic state updates for mute/deafen to eliminate tap delay
- Instant PTT visual feedback (no AnimatedContainer fade)
- Constant geometry across all states (no layout shift on toggle)
* fix(voice): preserve current PTT button format
* feat(voice): move mute/deafen controls into VoiceStatusChip
* fix(voice): ensure consistent chip height across mute states
Remove isSelected/selectedIcon from IconButtons inside VoiceStatusChip.
Material 3 toggle IconButtons (_SelectableIconButton) can vary in height
when the selected state changes due to tap target sizing. Use simple
conditional icons instead and set shrinkWrap tap target size with tight
constraints for stable 40x40 buttons regardless of state.
* fix(voice): remove leftover duplicate mute/deafen buttons in VoiceStatusChip
* fix(voice): replace unsafe stereo cast with bytemuck and localise talk-power tooltip
Replace the raw-pointer `&mut [(f32, f32)]` to `&mut [f32]` cast in
the oboe output callback with `bytemuck::cast_slice_mut`, eliminating
the unsafe block and relying on bytemuck compile-time NoUninit
verification instead.
Add voiceTalkPowerBlocked l10n key (en + zh) and replace the only
remaining hard-coded English tooltip in VoiceStatusChip with it.
