fix: read hardware audio status from V2 player instead of legacy

v2_get_hardware_audio_status was reading sample_rate/bit_depth from the
legacy player state, which is never updated since playback runs through
the V2 player (CoreBridge). Now reads from V2 player first, falls back
to legacy only if CoreBridge isn't initialized yet.
