fix(anki): close the timing review modal once main has dropped the review

Main ends a review on its own after the decision watchdog, on overlay
teardown, or when the modal window opened twice, but the renderer only
closed on a successful resolve. Every button then answered 'no longer
active' forever and the overlay stayed interactive over mpv. Stale
results now carry a typed flag and the modal closes on it.
