feat(api): search with Meilisearch (M2)

- artists, albums and tracks indexes are rebuilt from PostgreSQL next
  to the live ones and swapped in, so search keeps working; a rebuild
  runs on start, after every scan and when a source is removed
- transliteration fields (Кино ↔ kino) and a retry in the other
  keyboard layout (ghbdtn → привет) reported as corrected_query
- /search/suggest (3 artists, 3 albums, 5 tracks), /search by type
  with cursor pages, /admin/search/reindex; Meilisearch is part of
  /readyz
- found ids are hydrated from the catalog, so a lagging index never
  returns deleted entries
