Code Review
This pull request introduces a new API endpoint for deleting composers (DELETE /composers/{composerId}). However, a significant security concern has been identified regarding the authorization logic. The use of a hardcoded user ID (5L) for administrator identification is an insecure approach that could lead to privilege escalation. Beyond this, the current implementation also raises maintainability concerns due to the hardcoded ID in ComposerService and lacks comprehensive test cases in ComposerControllerTest for unauthorized access scenarios. It is strongly recommended to transition to a robust role-based access control (RBAC) system and add the necessary tests.

The authorization check relies on a hardcoded user ID (5L) to identify the administrator. This is a critical security vulnerability as user IDs are often predictable, potentially leading to privilege escalation if a regular user is assigned this ID. It also introduces maintainability issues, as this 'magic number' is difficult to understand and manage if admin policies change. It is strongly recommended to implement a proper Role-Based Access Control (RBAC) system. This involves adding a role field to the User entity and checking for an ADMIN role instead of a hardcoded ID. This will enhance both security and maintainability.

현재 테스트는 작곡가 삭제 성공 케이스(204 No Content)만 검증하고 있습니다. 하지만 서비스 로직에는 관리자(ID=5)만 삭제를 수행할 수 있는 권한 검사 로직이 포함되어 있습니다.
권한이 없는 사용자가 삭제를 시도했을 때 예상대로 403 Forbidden 응답을 반환하는지에 대한 테스트 케이스를 추가하여 코드의 안정성을 높이는 것이 좋습니다.
