AudioTrack table replaces AudioFile (Filename, Name, AssignedFrequency,
MD5, Selected, Order) — fixes relative-path bug in scrollerPage.go that
caused "file not found" for single-track selection.
Download goroutine now:
- Accepts *gorm.DB and updates AudioTrack.MD5 after each download.
- Treats checksums.md5 as source of truth: removes local files and DB
records not in the manifest (orphans).
- Strips "./" prefix from manifest filenames (GNU md5sum format).
AudioOptions.go seeds 14 AudioTrack records matching server checksums.md5.
List background quad width matches the widest item (+ padding), centered.
scrollerPage.go switchAudioForFrequency falls back to original/selected
audio when a frequency has no matching track or file. playOriginalAudio
is a no-op on repeat calls to avoid 5-second audio restart loop.
Fixes progress display: passes Max=0 during downloads so Home page shows
"x / X Files Downloaded" text instead of bogus "100.0%" percentage.
Downstream audio switching (DynamicAudio) verifies an AudioTrack exists
for the frequency before assigning it to a stream — frequencies without
a track (e.g. 528 Hz) gracefully use original audio instead.
