캐릭터 상세 조회 - 원작 번역 및 캐릭터 소개 일괄 번역 기능 구현

- `SeriesTranslationPayload.keywords` 타입을 `String`에서 `List<String>`으로 변경했습니다.
- `SeriesTranslationPayloadConverter`의 `convertToEntityAttribute`를 하위 호환 가능하도록 수정했습니다.
  - DB에 저장된 JSON에서 `keywords`가 과거 스키마(String)인 경우와 신규 스키마(List)를 모두 안전하게 파싱합니다.
  - 파싱 실패 또는 공백 입력 시 기본값을 사용합니다(`keywords = []`).
- `convertToDatabaseColumn`은 변경 없이 `ObjectMapper`로 직렬화하여 `keywords`가 배열로 저장됩니다.
