Fires the first time a game transitions from non-over to any over-state
(OVER/FINAL/OFF), so the notification lands when the clock runs out
rather than hours later when NHL statisticians stamp OFF. Shows the
winning team's logo with a "{TEAM} wins" title and final score body.
Deduped by game ID via gameEndsSent; cleared on resetForNewDay.
Dev menu: "Test Game Ended Notification" for manual trigger.
