Frank Stellmacher 568f3aeb7d test(api): subsonic.ts async endpoint contracts (F3 follow-up) (#549)
39 new tests targeting the response normalization paths the F3 PR (#544)
deferred. Mocks axios at the module boundary; pins:

- api() helper envelope: unwrap subsonic-response on status=ok, throw
  "Invalid response" without envelope, throw the server message on
  status=failed, throw a generic on failed-without-message, propagate
  network failures.
- song-array vs single-object normalization paths:
  - getMusicDirectory normalizes child (object -> [object]), empty -> [].
  - getMusicIndexes flattens index -> artist arrays (object or array).
  - getMusicFolders coerces numeric ids to strings + defaults name.
  - getRandomSongs pass-through behaviour pinned (no normalization --
    Navidrome always returns the array form).
- collection-shape contracts: getAlbum splits { album, songs } + empty
  fallback when album.song is absent, getStarred returns empty arrays
  on missing starred2 / missing fields / pass-through arrays.
- single endpoint behaviours: getSong null on failure, getTopSongs []
  + slice to 5, getArtists flatten + empty, search whitespace-query
  short-circuit (no HTTP), getAlbumInfo2 null on error, ping
  true/false based on status.
- pingWithCredentials (explicit-URL path): full response (type +
  serverVersion + openSubsonic), http:// prepend when scheme missing,
  trailing-slash strip before /rest/ping.view, ok=false on any
  failure / status=failed, openSubsonic defaults to false when omitted.

subsonic.ts coverage 12.66% -> 31.87% lines (+19pp). The remaining
surface lives in niche endpoints (playlist mutations, statistics
overview/aggregates, internet radio CRUD, cover-art uploads, ratings
prefetch). Not gate-eligible yet; a follow-up could push to ~60% but
diminishing returns relative to other backlog items.

Frontend suite: 412 -> 451 tests (+39).
