Dismiss expanded player window when closing video from the mini bar

The capsule close button (and context-menu close) only stopped playback and
cleared the queue, leaving the separate macOS player window open on a black
frame. Route both through a shared closeVideo() that also sets
isPlayerExpanded = false, mirroring PlaybackCommands.closeVideo, so the
player window is dismissed.
