### ISSUE
- Group: `server`
- Type: `feature`
- Detail: 라운지 위치정보 api 구현

### TODO
1. [x] 라운지 주소를 DB에서 가져오는 query 테스트
2. [x] 위치정보 controller 작성
3. [x] postman을 통한 테스트 진행

### Estimated time
### `3h`

Review the server entry point, the lounge-address database query, and the location-information controller; the issue provides no file paths or endpoint details. Re-run the query test and reproduce the Postman request to determine the current state. Done means the lounge address is returned correctly through the location-information API and the request is verified.
