fix(games): roll Stella Sora's day at 13:00 UTC-7 for every region

One worldwide server on a fixed UTC-7 resetting at 13:00 (20:00 UTC); the
app used the regional default. Source: Game-Time-Master, which lists the
zone as fixed rather than Pacific.

Re-labels the game-day of some already-logged ticks.
