fix(whatsapp-web): strip MIME parameters before matching in audio_mime_to_filename

Browse Source 
MIME strings like 'audio/webm; codecs=opus' were incorrectly matched by
the 'opus' branch (contains-check) before reaching the 'webm' branch,
returning 'voice.opus' instead of 'voice.webm'. This could cause the
Groq Whisper API to reject or misidentify the file format.

Fix: split on ';' to extract only the base MIME type, then match
exhaustively. Also add 'audio/x-wav' as a wav alias.

Adds a regression test: audio_mime_to_filename('audio/webm; codecs=opus')
must return 'voice.webm'.
