Game times were incorrectly using device timezone in several views.
Now all game time displays use the stadium's local timezone via
RichGame.localGameTime/localGameTimeShort properties.
Fixes:
- PDFGenerator: was using game.gameDate (midnight UTC) instead of actual time
- GameRowCompact: was formatting with device timezone
- TimelineGameRow: was using .formatted() with device timezone
Also adds Date+GameTime.swift extension for centralized timezone formatting.
