Root cause: Oboe capture at 48kHz with InputPreset::VoiceCommunication cannot open against a BT SCO device (only supports 8/16kHz). The stream silently falls back to builtin mic, delivering zeros. Fix: add bt_active flag to WzpOboeConfig. When set, capture skips setSampleRate and setInputPreset, letting the system route to BT SCO at its native rate. Oboe's SampleRateConversionQuality::Best resamples to 48kHz for our ring buffers. Playout uses Usage::Media in BT mode. New API: wzp_native_audio_start_bt() for BT mode, called from set_bluetooth_sco(on=true). Normal audio_start() restores the standard config when switching back to earpiece/speaker.
