[GWL-85] 서버 구조에 맞게 웹 소켓 연동 (#200)

* test: 서버 환경과 비슷하게 소켓 테스트 수정

- 테스트를 실환경으로 수정하면서 오류가 발생하는 것을 고칠 예정입니다.

* feat: test 코드에 맞게 MockWebSocketSession 기능 변경

* add: Socket 모델 debug 로그 추가

* fix: 헬스 데이터로 snapshot을 적용하는 코드가 누락된 점 수정

* style: 거리 데이터와 타이머 초 UI 수정

- 거리 데이터는 소수점 세 자리까지 보여줍니다.
- 타이머는 00분 00초로 시작합니다.

* delete: 불필요한 주석 제거
