Update Apps to Use Tab Navigation Where Supported

Both native-navigation and react-navigation implement a version of tabs (or swipeable-views) that could be used in the demo apps. The original thought was to make overall codebase as close to possible to each other to focus on higher level routing but one could argue that if the lib supports it, it should be used. 🤔

Start by locating the demo apps and their native-navigation and react-navigation entry points. Compare how each library exposes tabs or swipeable views, then determine which demos can use them while keeping higher-level routing comparable. Done means supported demo apps consistently use the library's tab navigation.
