Three index bugs in PlayQueueManager, two of which leave
PlayingItemIndex out of bounds, making every subsequent Buffering/Ready
request throw and leaving the group unusable until it empties:
- RemoveFromPlaylist did not compensate for removed items preceding the
playing item: removing the playing item together with earlier items
could select the wrong item or crash with an out-of-bounds index.
- Next/Previous on an empty playlist with RepeatOne/RepeatAll reported
success or set PlayingItemIndex to 0 on an empty list, crashing
downstream in Group and corrupting the index.
- SetPlayingItemByIndex accepted an index equal to the playlist count
(latent off-by-one, callers currently pre-validate).
When a client polls the HLS playlist (e.g. live.m3u8) after a live stream has
been disposed because its consumer count dropped to zero,
GetLiveStreamWithDirectStreamProvider returns a null MediaSource. The live
branch of GetStreamingState then dereferenced it unconditionally, throwing a
NullReferenceException and returning HTTP 500 for every poll until the client
re-opens the stream. Guard against the null MediaSource and throw
ResourceNotFoundException so the request returns 404 instead of crashing.
Fixes#17009

Added static method GetBaseItemKindsForCollectionType in ItemsController (moved from ContentFolderImageProvider to be shared)
Added AudioBook to GetRepresentativeItemTypes for CollectionType.books for consistency
Added GetBooks to GetUserItems for CollectionType.books which gets BaseItemKind.Book and BaseItemKind.AudioBook
Move GetBaseItemKindsForCollectionType to DtoExtensions
Cleaned up the missing null checks and used new collection expressions.
Associate Person to Book and AudioBook for related items.
When the server finishes starting, show "Jellyfin started successfully" with a
5-second "Redirecting in N…" countdown and a Cancel button instead of reloading
immediately. Cancel stops the countdown and the background refresh so the
startup output can be reviewed, and offers a "Continue to Jellyfin" button to
reload manually. The buttons use the web client's emby-button styling.
Also drop the transitional "Applying migrations" activity: it only showed
briefly while the pending migration set was read, or for the whole step when
nothing was pending, so startup now goes from "Preparing migrations" straight
into "Running migration X of Y".
