[feat] Add rectangular hover area tracking for queue overlay

Uses useMouse + useElementBounding from VueUse to detect hover over the
entire rectangular bounding box of the queue area (actionbar + overlay).

This approach is needed because QueueProgressOverlay has pointer-events-none
on its wrapper, which would create "holes" in hover detection with standard
mouseenter/mouseleave events.
