Add an Audio/voice directory with upload and preview support, and expose it in the console file manager so the structure now shows Configuration, Music, Voice, Beep, and Station.
Add an Audio/music path for uploaded music, keep the existing general audio directory as the Beep group, and update the console and music page so the file manager now shows Configuration, Music, Beep, and Station with matching upload and preview routes.
Allow the console and music page to upload common audio formats, expand music track detection and playback source selection beyond wav/dfpwm, and update station list name normalization so common extensions resolve consistently. Bump the station build to v1.0.6.
