외부 시퀀스 설계 완료

- 4개 주요 비즈니스 플로우 외부 시퀀스 다이어그램 작성
  * 사용자인증플로우: 회원가입, 로그인, 로그아웃
  * 이벤트생성플로우: AI 추천, 이미지 생성, 다중 채널 배포
  * 고객참여플로우: 이벤트 참여, 당첨자 추첨
  * 성과분석플로우: 실시간 대시보드 조회

- Event-Driven 아키텍처 반영 (Kafka Event Topics + Job Topics)
- Resilience 패턴 전면 적용 (Circuit Breaker, Retry, Timeout, Fallback)
- Cache-Aside 패턴 적용 (Redis 캐싱)
- 논리 아키텍처 및 유저스토리 기반 설계
