Group calls with at least eight participants can unexpectedly mute an unmuted speaker when the peer connection reconnects. Apply the automatic join mute only on the first connection of each call, preserving the user-selected microphone state across subsequent connection callbacks.
Replace the external AudioSwitch implementation with in-app audio routing for communication devices, Bluetooth SCO fallback, and restoration of the previous audio state. Both changes are based on the latest merged master.
Validation:
:app:compileGooglePlayDebugKotlinpasses for the combined branch. Multi-party reconnects and Bluetooth/device switching still need physical-device regression testing.
