fix(auth): add token expiry check in start_game

Check if the Microsoft account token is expired before attempting to
launch the game. If expired, attempt to refresh using the refresh_token.
If refresh fails, return an error instructing the user to login again.

Also removed #[allow(dead_code)] from is_token_expired since it's
now actively used.
