Add thank-you ending screen and a run timer

Defeating the bear (the run's final boss) now plays a dedicated
"Thank You For Playing" clip on the completion screen instead of the
generic bull-win video, with the run's finish time shown in place of
the usual "Bull Won!" title.

A run clock also starts when the player enters the arena (the run's
first fight), shown top-left on desktop only, and freezes the instant
the bear falls. Re-entering the arena after finishing a run restarts
the clock instead of leaving it stuck on the previous run's time.
