Subject: [PATCH] Add OAuth2Error class and corresponding tests

- Introduced a new error class `OAuth2Error` that extends `AppError`, providing a specific error handling mechanism for OAuth2-related issues.
- Added unit tests for `OAuth2Error` to verify the correct setting of message, name, and error code.

These changes enhance error management in the application by allowing for more granular handling of OAuth2 errors.
