WinnerController Swagger 문서화 추가 및 이벤트/참여자 예외 처리 개선

- WinnerController에 Swagger 어노테이션 추가 (Operation, Parameter, ParameterObject) - 당첨자 목록 조회 API 기본 정렬 설정 (winnerRank ASC, size=20) - ParticipationService에서 이벤트/참여자 구분 로직 개선 - 이벤트 없음: EventNotFoundException 발생 - 참여자 없음: ParticipantNotFoundException 발생 - EventCacheService 제거 (Redis 기반 검증에서 DB 기반 검증으로 변경) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
