This commit implements the `UseUserAccessGroup` method in the Firebase C++ Auth SDK. This method is iOS-only and allows developers to specify a keychain access group for sharing authentication state across multiple apps from the same publisher. - Added the public API `UseUserAccessGroup(const char* access_group)` to `firebase::auth::Auth`. - Implemented the Objective-C wrapper in `auth_ios.mm` to call `[FIRAuth useUserAccessGroup:error:]`. - Added stub implementations for Android and Desktop platforms that log a warning and return `kAuthErrorNone`. - Included comprehensive Doxygen comments for the new API in `auth.h`.

There was a problem hiding this comment.
The actual stub methods return kAuthErrorNone, please fix this comment.
