hotfix - docker 관련 수정

[roode1017]

Summary by CodeRabbit

• Chores
  • 런타임 베이스 이미지를 경량 JRE로 전환하여 컨테이너 이미지 크기를 줄이고 배포/스케일링 속도를 개선했습니다. 경량 기반으로 메모리 사용량 감소와 시작 시간 단축이 기대됩니다.
  • API 서비스의 불필요한 의존성 대기 조건을 제거하여 기동 순서를 단순화했습니다. 그 결과, 서비스가 외부 컴포넌트 상태와 무관하게 더 빠르게 시작될 수 있어 초기 가용성이 향상됩니다.

Poem

알파인 바람에 JRE가 살짝,
토끼는 컨테이너 위로 깡충 깡충.
카프카 기다림은 이제는 끝,
API 둘이 먼저 출발, 쓩—쓩!
배포 들판에 파란 파도, 빌드엔 평온만 남았지. 🐇🚀
