Restructure the narrow / mobile body layout around three principles
(Hoober thumb-zone research validated, Material 3 components):
1. Channel tree gets ~85% of the screen height.
2. Live voice state is always visible in a 2-line status chip
above the PTT button.
3. PTT button is wide, bottom-anchored (thumb-natural lower zone).
4. Frequent toggles (mic mute, headset mute, voice settings) live
in the AppBar so they don't compete with the channel tree.
5. Non-essential live readouts (level meter, TX/RX, capability
badge) live in a modal sheet opened by tapping the status chip
-- progressive disclosure.
apps/chanora_flutter/lib/widgets/voice_compact.dart (new file)
* VoiceStatusChip: 2-line live readout. Line 1 = mode + bind hint;
Line 2 = release-tail + 'Mic on/off'. Tap opens
showVoiceDetailsSheet.
* VoicePttButton: 56 dp wide bottom-anchored Push to Talk button.
Same touch-and-hold gestures as the previous _PttHoldButton.
* showVoiceDetailsSheet: modal bottom sheet with mode recap +
bind/tail hint + level meter + TX/RX counts + PTT capability
badge (desktop-only).
apps/chanora_flutter/lib/main.dart
* AppBar gains mic-mute, headset-mute, voice-settings icons when
in voice channel AND MediaQuery width < 840 dp (mobile only).
Wide mode keeps these controls inside the existing VoiceBar
widget unchanged.
* AppBar title becomes a Row of 'app name + channel chip' when
in voice channel.
* Narrow-mode body restructured: Expanded(channelTree) +
VoiceStatusChip + VoicePttButton (latter only when in voice
channel AND PTT mode). The old narrow-mode VoiceBar is gone;
wide-mode VoiceBar is unchanged.
* New _onOpenVoiceDetailsSheet handler bridges the chip-tap to
showVoiceDetailsSheet.
* New top-level helper _isTouchOnlyPttHost mirrors the helpers
in widgets/voice_bar.dart and widgets/voice_settings.dart so
the AppBar + narrow-mode chip can branch consistently.
apps/chanora_flutter/lib/l10n/app_en.arb
apps/chanora_flutter/lib/l10n/app_zh.arb
apps/chanora_flutter/lib/l10n/generated/* (regenerated)
* New string voicePttHoldHint = 'Hold the button' / '按住按钮'.
Surfaced in line 1 of VoiceStatusChip on touch-only hosts and
in the modal sheet's PTT line where the desktop equivalent
would name a bound key.
Wide-mode (>= 840 dp) layout intentionally unchanged so the
signed-off rc.8 desktop verification still applies.
flutter analyze: clean (6 pre-existing Radio.groupValue infos).
Local cargo + flutter analyze pass; Mac was offline at commit
time so iOS device build verification is pending the next sync.
