Fix click events blocked by Button1Released early return

Unix SGR mouse driver sends Button1Released and Button1Clicked as
combined flags in a single event. The Button1Released handler in
ListControl and TableControl had an unconditional return false when
no scrollbar drag was active, preventing Button1Clicked from ever
being processed. This broke click-based selection in ServerHub dialogs.
