* fix(playback): pin queue streams, cover art, and library links to queue server
When the active server changes while a queue from another server is playing,
keep streams and UI on queueServerId; switch back for artist/album links and
queue or player-bar context menus.
* fix(playback): switch to queue server when opening Now Playing
Ensure active server matches queueServerId before Subsonic fetches on the
Now Playing page, mobile player route, and queue info panel; scope caches
by server id.
* docs(credits): mention Now Playing in PR #717 contribution line
* fix(playback): route scrobble and queue sync to queue server
Address PR review: apiForServer for scrobble/now-playing/savePlayQueue,
clear queueServerId on server removal, mini-player queueServerId sync,
block cross-server enqueue with toast, and regression tests.
* fix(ui): place playlist context submenus flush to trigger row
Use left/right/top 100% instead of calc(100% + 4px) so there is no dead
gap when moving the pointer from Add to playlist into the submenu.
* fix(ui): defer closing playlist submenu on trigger mouseleave
Use a short timer and :hover on the trigger row so slow moves across
border/subpixel gaps still reach the nested submenu; cancel timer on
re-enter and when the context menu closes.
