Implement OAuth account management methods and enhance user provider functionality

- Added methods for creating, retrieving, updating, and deleting OAuth accounts, improving user authentication capabilities.
- Introduced default OAuth account fields and options for better configuration management.
- Enhanced error handling for OAuth account operations, ensuring robust feedback for failures.
- Updated tests to ensure unique identifiers and improved cleanup processes for test data, maintaining a clean testing environment.
