fix(ui): hold the provider play action and the reset row during their busy windows

The downloaded movie's provider action stays enabled while a start was
pending, so a second press could start beside a launch already inside
the player IPC. The series menu's reset row stayed enabled while a
watched batch persisted, although the hosts refuse the reset meanwhile.
