[#54] 애플리케이션 배포 (#55)

<!-- 제목 양식 -->
<!-- [이슈번호] 작업 요약 (예시: [#10] Gitea 템플릿 생성) -->

## 📝 관련 이슈 및 PR

**PR과 관련된 이슈 번호**
- #54

## ✨ 작업 내용
<!-- 어떤 작업을 했는지 알려주세요! -->
- 애플리케이션 배포
- 1차 배포에서 각 Service의 Trace가 구분이 되지 않아 XxxService 클래스에 \@Observation을 적용하는 AOP 추가
- 불필요하게 느껴지는 Prometheus Actuator 요청과 스케쥴링 작업 Tracing 제외
- 애플리케이션이 UTC로 배포됨에 따라 발생하는 문제 해결을 위해 LocalDateTime, OffsetDateTime -> Instant 타입 변경 및 LocalDate, LocalTime은 KST로 비교하도록 수정
- 기존 로그의 가독성이 좋지 않아, 로그 메시지가 가장 먼저 보이도록 형식 수정

## 🧪 테스트
<!-- 어떤 테스트를 생각했고 진행했는지 알려주세요! -->
- 실제 웹에 접속하여 전체적인 기능 점검
- 예약 처리 로직에서 미숙한 부분이 발견되어 다음 작업은 예약 처리 로직 개선 예정

## 📚 참고 자료 및 기타
<!-- 참고한 자료, 또는 논의할 사항이 있다면 알려주세요! -->
