This PR introduces a complete authentication flow, including user registration and login. It also addresses a logic error in password verification and ensures high code coverage through unit and integration tests.
Key Changes:
Security Fix: Corrected PasswordEncoderBasicService.matches() logic. Previously, it was double-encoding the raw password, causing authentication to always fail.
Auth Flow: * Implemented loginUser endpoint returning JWT.
Error Handling: Created dedicated exceptions for auth failures to improve API clarity.
