fix(voice_mode): detect audio in WSL when sd.query_devices() returns empty list but PULSE_SERVER is set

Browse Source 
In WSL2, sounddevice.query_devices() returns [] even when the
PulseAudio bridge is functional. The existing code already handled
the case where the query itself raises an exception, but it missed
the empty-list case.

This change treats an empty device list as non-fatal in WSL when
PULSE_SERVER is configured, matching the existing exception-handler
behavior.

Fixes: WSL users seeing 'No audio input/output devices detected'
even though paplay/arecord work fine.
