fix(audio): clean up ALSA device names for display on Linux

Browse Source 
Raw ALSA names like "sysdefault:CARD=U192k" are replaced with
readable labels ("U192k") in the device dropdown. The underlying
value stays unchanged so rodio can still open the correct device.

Covers: sysdefault, hw, plughw, iec958, front, surround prefixes.
Names without ALSA structure (pipewire, pulse, default) are kept as-is.
