Cross-platform web user interface

Currently we are only targeting Windows systems, but RePlays has the potential for cross-platform capabilities. However, WebView2 is currently only supported by Windows, and the development on getting it ported to Linux and MacOS seem to be at a standstill.

The interest for getting RePlays to work on Linux is for it to work on the Steam Deck.

After some research, we could invest our time porting all of the user interface to Blazor/MAUI. But this does not seem ideal because we would not be able to reuse any parts of the React solution. The entire MVC may need to be redesigned and the interface would need to be rebuilt from the ground up. I do not think this is worth the trouble.

Instead, I am leaning towards using Photino, which will try to use the native browser solution for the targeted system. For example: if targeting Windows it will use WebView2, targeting Linux it will use WebKitGTK+ 2.
