The Download Discography modal exposed only Albums/EPs/Singles, its EPs toggle did
nothing, and Live/Compilations/Featured were missing — so you couldn't fine-filter
a bulk download the way Artist Detail lets you browse.
Root cause: the modal's endpoint (/api/artist/<id>/discography) used the base
get_artist_discography, which lumps EPs into singles, and the modal only read
{albums, singles} — so the EPs bucket was always empty (dead toggle). It also had
no content-type (Live/Compilation/Featured) classification at all.
- Backend: the endpoint now uses get_artist_detail_discography — the SAME split
Artist Detail uses — and returns a separate `eps` list.
- Frontend: read `eps`; tag each card with data-is-live/compilation/featured via a
new shared _classifyReleaseContent() (also adopted by the Artist Detail cards so
the two can't drift); add Live/Compilations/Featured filter buttons; combined
category+content filtering. The download payload is built from VISIBLE checked
cards, so every toggle now actually changes what downloads.
- Regression test: get_artist_detail_discography splits an EP into the eps bucket.
