fix(lists): tick count down when media leaves a listHEADmain

On revalidation the {#await} branch swaps and remounts CleanAnimeList,
resetting NumberTicker's tween to 0 so it always counted up. Persist the
last displayed count in AnimeListTemplate (which survives the remount) and
feed it as the ticker's start, so the count animates in the real
direction: down when an item leaves due/upcoming, up when one arrives.
