Merge live game data into KBO schedule results for today.

- KBO 일정 조회 시 오늘 날짜의 경기에 대해 실시간 점수와 경기 상태를 병합하는 기능을 추가했습니다.
- `GameStatus` 타입에 'live'를 추가하고, 게임센터 API 데이터를 기반으로 상태를 변환하는 로직을 구현했습니다.
- 외부 API 연동 시 발생할 수 있는 일시적인 오류(503 등)에 대비하여 예외 발생 시 기존 캐시 데이터를 반환하도록 예외 처리를 적용했습니다.
- 경기 ID 또는 팀 정보와 시간을 조합한 복합 키를 사용하여 스케줄 데이터와 실시간 데이터를 정확하게 매칭합니다.
