Use the musicAudioFiles form field on music.html so the page matches the multer configuration for /api/upload/music-audio and stops returning Unexpected field.
Merge stations with the same station code and platform into one logical target, and expand music and temp broadcast playback to all online slave nodes while the console and picker UIs show grouped station entries with node counts.
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.
