fix(data): populate stadium timezone in scrapers and CloudKit sync

Stadium timezones were always null because scrapers weren't passing
the timezone from STADIUM_MAPPINGS to the Stadium constructor. This
fix propagates timezone data through the entire pipeline: scrapers,
CloudKit uploader, and Swift CloudKit model.
