## Summary by CodeRabbit

* **New Features**
* The Apple OAuth provider is now available only for clients version
0.22.0 or higher.
* Client version detection has been improved by extracting version
information from request headers.

* **Bug Fixes**
* Ensured that the Apple OAuth provider is hidden for clients below
version 0.22.0.

* **Tests**
* Added comprehensive end-to-end and utility tests for OAuth provider
selection and client version extraction.
