feat(metadata): implement single-track metadata editor page (§A7)

Replace the placeholder with a controlled form for title/artist/album/
year/genre/track number, an AcoustID "find matches" action showing
ranked candidates with confidence, a diff/apply picker, a re-enrich
button, and save via PUT /metadata. Adds matches/apply API endpoints,
mappers, types, and en/ru i18n strings. Batch editor remains a
placeholder (deferred).
