This PR introduces a comprehensive set of UI test cases for the ContentView control, validating its behavior across a wide range of properties and interaction scenarios. The tests cover support for different content types such as Layout and ContentView ensuring they are displayed and updated correctly. The properties tested includeContent, IsEnabled, IsVisible, BackgroundColor, HeightRequest, WidthRequest, FlowDirection, HasShadow, ContentView, ControlTemplate as well as custom bindings like CardTitle, CardColor, IconImageSource, DefaultLabelText, and ContentLabel. In addition, the tests validate dynamic content replacement and binding updates, confirming consistent and reliable ContentView behavior across all supported platforms.
