Updated `CreateWindow` to use simplified object instantiation. Replaced `DisplayAlert` with `DisplayAlertAsync` across files to improve asynchronous handling. Refactored null checks in `TapGestureRecognizer_OnTapped` using the null-conditional operator. Simplified class and interface definitions by removing redundant braces. Streamlined `MainApplication` constructor and removed unused imports in `TestViewModel`. These changes enhance readability, maintainability, and modernize the codebase.

The method name DisplayAlertAsync does not exist in the standard .NET MAUI ContentPage API. The correct method name is DisplayAlert. This change will cause compilation errors unless a custom extension method exists.
