Deluan Quintão acd69f6a4f feat(playlist): support #EXTALBUMARTURL directive and sidecar images (#5131)
* feat(playlist): add migration for playlist image field rename and external URL

* refactor(playlist): rename ImageFile to UploadedImage and ArtworkPath to UploadedImagePath

Rename playlist model fields and methods for clarity in preparation for
adding external image URL and sidecar image support. Add the new
ExternalImageURL field to the Playlist model.

* feat(playlist): parse #EXTALBUMARTURL directive in M3U imports

* feat(playlist): always sync ExternalImageURL on re-scan, preserve UploadedImage

* feat(artwork): add sidecar image discovery and cache invalidation for playlists

Add playlist sidecar image support to the artwork reader fallback chain.
A sidecar image (e.g., MyPlaylist.jpg next to MyPlaylist.m3u) is discovered
via case-insensitive base name matching using model.IsImageFile(). Cache
invalidation uses max(playlist.UpdatedAt, imageFile.ModTime()) to bust
stale artwork when sidecar or ExternalImageURL local files change.

* feat(artwork): add external image URL source to playlist artwork reader

Add fromPlaylistExternalImage source function that resolves playlist
cover art from ExternalImageURL, supporting both HTTP(S) URLs (via
the existing fromURL helper) and local file paths (via os.Open).
Insert it in the Reader() fallback chain between sidecar and tiled cover.

* refactor(artwork): simplify playlist artwork source functions

Extract shared fromLocalFile helper, use url.Parse for scheme check,
and collapse sidecar directory scan conditions.

* test(artwork): remove redundant fromPlaylistSidecar tests

These tests duplicated scenarios already covered by findPlaylistSidecarPath
tests combined with fromLocalFile (tested via fromPlaylistExternalImage).
After refactoring fromPlaylistSidecar to a one-liner composing those two
functions, the wrapper tests add no value.

* fix(playlist): address security review comments from PR #5131:

- Use url.PathUnescape instead of url.QueryUnescape for file:// URLs so
  that '+' in filenames is preserved (not decoded as space).
- Validate all local image paths (file://, absolute, relative) against
  known library boundaries via libraryMatcher, rejecting paths outside
  any configured library.
- Harden #EXTALBUMARTURL against path traversal and SSRF by adding EnableM3UExternalAlbumArt config flag (default false, also
  disabled by EnableExternalServices=false) to gate HTTP(S) URL storage
  at parse time and fetching at read time (defense in depth).
- Log a warning when os.ReadDir fails in findPlaylistSidecarPath for
  diagnosability.
- Extract resolveLocalPath helper to simplify resolveImageURL.

Deluan Quintão 7ad2907719 refactor: move playlist business logic from repositories to service layer (#5027)
* refactor: move playlist business logic from repositories to core.Playlists service

Move authorization, permission checks, and orchestration logic from
playlist repositories to the core.Playlists service, following the
existing pattern used by core.Share and core.Library.

Changes:
- Expand core.Playlists interface with read, mutation, track management,
  and REST adapter methods
- Add playlistRepositoryWrapper for REST Save/Update/Delete with
  permission checks (follows Share/Library pattern)
- Simplify persistence/playlist_repository.go: remove isWritable(),
  auth checks from Delete()/Put()/updatePlaylist()
- Simplify persistence/playlist_track_repository.go: remove
  isTracksEditable() and permission checks from Add/Delete/Reorder
- Update Subsonic API handlers to route through service
- Update Native API handlers to accept core.Playlists instead of
  model.DataStore

* test: add coverage for playlist service methods and REST wrapper

Add 30 new tests covering the service methods added during the playlist
refactoring:

- Delete: owner, admin, denied, not found
- Create: new playlist, replace tracks, admin bypass, denied, not found
- AddTracks: owner, admin, denied, smart playlist, not found
- RemoveTracks: owner, smart playlist denied, non-owner denied
- ReorderTrack: owner, smart playlist denied
- NewRepository wrapper: Save (owner assignment, ID clearing),
  Update (owner, admin, denied, ownership change, not found),
  Delete (delegation with permission checks)

Expand mockedPlaylistRepo with Get, Delete, Tracks, GetWithTracks, and
rest.Persistable methods. Add mockedPlaylistTrackRepo for track
operation verification.

* fix: add authorization check to playlist Update method

Added ownership verification to the Subsonic Update endpoint in the
playlist service layer. The authorization check was present in the old
repository code but was not carried over during the refactoring to the
service layer, allowing any authenticated user to modify playlists they
don't own via the Subsonic API. Also added corresponding tests for the
Update method's permission logic.

* refactor: improve playlist permission checks and error handling, add e2e tests

* refactor: rename playlists_internal_test.go to parse_m3u_test.go and update tests; add new parse_nsp.go and rest_adapter.go files

* fix: block track mutations on smart playlists in Create and Update

Create now rejects replacing tracks on smart playlists (pre-existing
gap). Update now uses checkTracksEditable instead of checkWritable
when track changes are requested, restoring the protection that was
removed from the repository layer during the refactoring. Metadata-only
updates on smart playlists remain allowed.

* test: add smart playlist protection tests to ensure readonly behavior and mutation restrictions

* refactor: optimize playlist track renumbering with CTE-based UPDATE

Replace the DELETE + re-INSERT renumbering strategy with a two-step
UPDATE approach using a materialized CTE and ROW_NUMBER() window
function. The previous approach (SELECT all IDs, DELETE all tracks,
re-INSERT in chunks of 200) required 13 SQL operations for a 2000-track
playlist. The new approach uses just 2 UPDATEs: first negating all IDs
to clear the positive space, then assigning sequential positions via
UPDATE...FROM with a CTE. This avoids the UNIQUE constraint violations
that affected the original correlated subquery while reducing per-delete
request time from ~110ms to ~12ms on a 2000-track playlist.
