feat: Android Oboe voice backend — WebRTC APM, VAD, HW/SW toggle, BBCode welcome, link trust, foreground task

Audio engine (Rust):
- Android Oboe: WebRTC APM (AEC/NS/AGC/HPF) + TEN/Silero ONNX VAD
- Hardware effects (JNI) with software fallback per-effect
- Render reference buffer for AEC between output/capture callbacks
- Voice activity gate: suppress transmission when speaker muted (all platforms)
- Audio focus (SDD-109) + Bluetooth SCO (SDD-110) via JNI
- ONNX Runtime 1.26 via ort 2.0.0-rc.12 (down from rc.10, ndarray 0.17)
- VAD worker channel capacity 8→32, initial seq u64::MAX (warm-up fix)
- TEN VAD default backend (was Silero)
- Platform→WebrtcApm resolution after hardware binding
- oboe-rs edisonjwa fork with get_raw_session_id()

Android Kotlin:
- AndroidAudioFocusController + AndroidBluetoothScoController
- AndroidAudioLifecycleController (route changes to Flutter)
- ProGuard rules for new controllers

Flutter UI:
- VoiceSettings: Android HW/SW toggle (Platform auto / WebRTC APM)
- VoiceStatusChip: mute warning border + Speaker muted label
- BBCode welcome message parser (BbCodeText, case-insensitive)
- Welcome message foldable (expanded by default)
- Link trust dialog (domain wildcards, SharedPreferences)
- HapticFeedback on voice sheet opener
- Server name in AppBar, version v0.1.0
- Default channel (id=1) visible, serverquery clients hidden
- flutter_foreground_task integration

Config:
- ort load-dynamic on all non-iOS (Android/Linux/Windows)
- ONNX Runtime AAR 1.26.0
- ndarray moved to common deps (was Apple-only)
