feat(cms): replace track audio in edit form, gate last-track delete

Browse Source 
Swap a track's audio by EntryKey (metadata/release/position preserved, waveform regenerated); hide per-track remove on a release's sole persisted track so it can only be replaced or release-deleted.

@* Replace audio: existing (persisted) rows only. New rows still pick their WAV
via the file input above, so a replace control there would be redundant. A
native <label for> drives a per-row hidden InputFile — clicking the icon
opens that row's picker with zero JS (no eval, no programmatic .click()). *@
