## Summary by CodeRabbit

* **New Features**
  * Added a new query to check if Single Sign-On (SSO) is enabled.
* Updated UI components to dynamically reflect SSO availability via live
data.
* **Refactor**
* Streamlined internal handling of SSO status detection for improved
reliability and maintainability.
* **Tests**
* Enhanced tests for SSO button behavior with mocked live data and added
edge case coverage for SSO callback handling.
