Deluan 9ce51cf575 perf(artwork): fetch only IDs for backfill enumeration
Backfill enumerated every album, artist, playlist and radio via GetAll
and mapped out just the ID. GetAll materializes full entities (library
joins, participant/stats/tags JSON, annotation, artwork hydration), so on
a large library it loaded tens of thousands of heavy structs only to read
one field each — spiking transient RSS to ~1GB during the one-time
upgrade backfill, a memory risk on small NAS/Pi hardware.

Add GetAllIDs to the album, artist, playlist and radio repositories: it
reuses each repo's base row-set filter (library visibility, artist
content join, playlist userFilter) but projects only id, skipping the
heavy columns and post-processing. A per-repo parity test asserts
GetAllIDs returns exactly the same id set as GetAll.

Verified on a 727MB / 29k-artist production DB copy: peak RSS during
backfill dropped from ~1012MB to ~89MB, file descriptors flat, same
36,138 items enqueued.
