Investigate using GenUI's GRouter component for better navigation between multiple app screens

Currently we use a few different in-app navigation widgets, but none of them are great. For example, the stack navigation widget is used to move between the rooms list and a room screen for the mobile view, but it has several issues and is not a true navigation "stack", i.e., you can't programmatically jump to a specific screen easily, you can go back and forward easily between screens.

GenUI offers a series of basic widgets implemented directly atop Makepad, which are intended to be easier to use than Makepad directly. We should investigate whether the GenUI GRouter component would be a suitable choice for our navigation needs, as it looks promising.

Here's an example of a small application that uses GenUI, specifically the GRouter component
