fix: don't label a FINAL playoff card as CLINCHER — those stakes belong to the next game

seriesStatus updates with the just-played game's win, so once a card goes
FINAL the is_clincher / is_game7 / is_pivotal predicates point at the
upcoming game. Gate the stake badge, stake blurb, and elimination_count
tally on a non-FINAL gameState so a completed Game 3 that left the series
3-0 reads "Flyers lead 3-0" instead of "Flyers can close it out — Game 3."
