Enhance OAuth guard with authorized info handling and ACL integration

- Updated the OAuth guard to set authorized information in the context using the new authorized package.
- Refactored the GetAuthorizedInfo function to utilize the authorized.GetInfo method, improving clarity and maintainability.
- Enhanced the ACL implementation by adding scope resolution logic in the Enforce method, ensuring proper access control based on user roles and scopes.
- Improved error handling and logging during ACL operations, providing better insights into access decisions.
