Ctrl-X now removes the track from the playlist right away (so it visibly
leaves) and a paste re-inserts it at the target — replacing the earlier
deferred-move design (dropped move_tracks_between_playlists and the MIME
cut flag). A cut from the library is still just a copy. Separately, a
left-click on any scrollbar trough now jumps to that spot instead of
paging, via an app-wide ClickToJumpScrollStyle proxy.
