apps/chanora_flutter/lib/services/audio_lifecycle_service.dart: extend parseBridgeAudioRoute to handle 'UsbHeadset' (maps to wiredHeadset — USB audio is functionally a wired-class device, matching AndroidAudioLifecycleController.classifyCurrentRoute's own preference ordering at line 176) and 'Hdmi' (maps to unknown — HDMI is a display-out transport, not a voice-call audio path; no existing BridgeAudioRoute variant fits; safer to leave as unknown than to misclassify as Speaker). Previously these Android-emitted strings hit the default branch and silently became BridgeAudioRoute.unknown.
apps/chanora_flutter/test/services/audio_lifecycle_service_test.dart: split the existing single test into three — iOS-classified strings (preserved), Android UsbHeadset (new), Android Hdmi (new). flutter test: 3 passed, 0 failed.
