feat(server/m7-353): admin endpoints for cover refetch (per-album + bulk)

Adds POST /api/admin/albums/{id}/cover/refetch (synchronous single-album retry) and POST /api/admin/covers/refetch-missing (async bulk drain). Wires coverart.Enricher through server.New → api.Mount → handlers struct. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
