없는 사물함 요청이 500으로 응답됩니다.

lockerId는 클라이언트 요청 본문에서 옵니다. 클라이언트가 임의의 값이나 삭제된 사물함 ID를 보낼 수 있습니다. 이 경우 IllegalArgumentException이 발생하고, 응답은 500이 됩니다. PR 설명에도 이 동작이 한계로 적혀 있습니다. path instructions는 "예외는 BusinessException 계층 + ErrorCode로 던진다"고 규정합니다. LockerErrorCode에 LOCKER_NOT_FOUND(NOT_FOUND)를 추가하고, 이 코드로 BusinessException을 던지세요. AppLockerApi의 @ApiErrorCode 목록도 함께 갱신하세요.

수정 예시
-            .orElseThrow(() -> new IllegalArgumentException("존재하지 않는 사물함입니다. lockerId=" + lockerId));
+            .orElseThrow(() -> new BusinessException(LockerErrorCode.LOCKER_NOT_FOUND));

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
Locker locker = lockerRepository.findLockerById(lockerId)
.orElseThrow(() -> new IllegalArgumentException("존재하지 않는 사물함입니다. lockerId=" + lockerId));
Locker locker = lockerRepository.findLockerById(lockerId)
.orElseThrow(() -> new BusinessException(LockerErrorCode.LOCKER_NOT_FOUND));

Update the locker lookup in LockerApplicationServiceImpl to throw
BusinessException with a new LockerErrorCode.LOCKER_NOT_FOUND mapped to
NOT_FOUND instead of IllegalArgumentException; add LOCKER_NOT_FOUND to
AppLockerApi’s @ApiErrorCode list.
