Add comprehensive tests for Gacha Credits, Auth, and User services

- Implement tests for GachaCreditsService including creation, retrieval, updating, and deletion of gacha credits.
- Add tests for AuthController covering user login, registration, email verification, and error handling for invalid credentials.
- Enhance AuthService tests to include login, registration, email verification, OTP resend, password reset, and token refresh functionalities.
- Create tests for UsersService to validate user creation, retrieval, updating, deletion, and fetching by email.
- Ensure all tests utilize a consistent setup and teardown process for database interactions.
