A query sorted by a user-dependent key (PlayCount, IsFavoriteOrLiked,
DatePlayed, IsPlayed, IsUnplayed) but carrying no User caused a
NullReferenceException inside UserDataManager.GetUserData, surfacing as
"Failed to compare two elements in the array" (InvalidOperationException
wrapping the NRE from the LINQ sort) and 500-ing the /Items request.
Root cause: LibraryManager.GetComparer assigned comparer.User = user
without a null guard, so PlayCountComparer.GetValue called
UserDataManager.GetUserData(null, item), dereferencing user.Id.
Two-part fix:
- LibraryManager.GetComparer: when user is null and the sort key requires a
user (IUserBaseItemComparer), substitute the SortName comparer so the
result stays deterministic instead of 500-ing. SortName is the project's
canonical tiebreaker (ItemsController injects it for album-by-artist).
- UserDataManager.GetUserData: ArgumentNullException.ThrowIfNull(user) as
defense in depth (matches the existing guards on the SaveUserData
overloads in the same file). On master this overload was rewritten to use
ResolveUserDataRow, so the NRE dereferences user.Id rather than
user.InternalId as on the release branch — same bug, different line.
Also fixes DateLastMediaAddedComparer being statically mis-tagged as
IUserBaseItemComparer: its GetDate is static and never reads User, so it
does not need one. Without this, the SortName fallback above would wrongly
engage for DateLastContentAdded on anonymous queries (returning SortName
order instead of date order). Re-tagged to IBaseItemComparer and dropped the
unused User/UserManager/UserDataManager properties.
Tests:
- UserDataManagerTests.GetUserData_NullUser_ThrowsArgumentNullException:
reproduces the crash (NRE -> now ArgumentNullException). Added to master's
existing UserDataManagerTests.
- LibraryManagerSortTests.Sort_UserDependentKey_NullUser_FallsBackToSortNameWithoutThrowing:
Sort with a user-dependent key + null user no longer throws and returns
items ordered by the SortName fallback (direction preserved).
- LibraryManagerSortTests.Sort_DateLastContentAdded_NullUser_OrdersByDateNotSortName:
guards that DateLastContentAdded still sorts by date with no user (fixture
chosen so date-desc and SortName-desc disagree, so a revert is caught).

Fixes#17393
Adds tvdb alias for tvdbid and imdb alias for imdbid.
It also fixes an issue where tmdb alias was being ignored
if it was followed by something like "tmdbidfoo".
The same issue prevented imdb pattern matching from
working, if it was followed by something like "imdbidfoo".
It also allows for detecting the first matching occurence,
whether it was an alias or not.
Finally, it ignores attributes with values consisting of only whitespaces.

Season and episode directories/files can now include provider ID
attributes in their names (e.g. "Season 01 [tvdbid=22222]" or
"Show S01E01 [tmdbid=99999].mkv"), consistent with the existing
behavior for series folders.
Supported providers: imdbid, tvdbid, tvmazeid, tmdbid.
Adds TmdbSeasonExternalId and TmdbEpisodeExternalId so that
the TMDB season and episode IDs are surfaced in the metadata editor.
Seasons do not have their own IMDb IDs, so we don't support imdbid parsing
in SeasonResolver. Instead, generate IMDb season URLs via
ImdbExternalUrlProvider using the parent series' IMDb ID and the
season number, matching the IMDb URL format:
imdb.com/title/{seriesId}/episodes/?season={N}
Add tests for the ExternalUrlProviders.
