refactor: update match time utilities and improve local match window logic

- Introduced new functions `isInLocalTodayMatchWindow` and `isAfterLocalTodayMatchWindow` to enhance match time checks.
- Replaced the deprecated `dayKeyInTimeZone` function with `isInLocalTodayMatchWindow` in the PlayerController.
- Updated related tests and utility exports to reflect the new naming conventions.
- Improved handling of local match windows in various components for better accuracy.
