Add deeplinks for checking/validation

Add deep links to top level destinations and a feature sub screen and check that the navigation and back stack behave as expected.

Why

We need to test the built in deep link behaviour of the nav controller is suitable for our use case.

Example use cases:

Push notifications (e.g. click and it takes you to a page in the app)
IDV journey (e.g. start IDV on web and go to app)
Wallet journey (e.g. on web click to add this document to your wallet)
What's new (e.g. we launch a feature and promote it in the app)

The ability to send data from a web URL deeplink has been proved here - see video below. This accounts for the IDV and Wallet journeys.

Data (single element, multiple elements, or serialised objects) can be sent by adding it in the NavHost routes, like this...

composable("about",
    deepLinks = listOf( /* create deeplink */ ),
    arguments = listOf(
        navArgument("id") {
            type = NavType.IntType
            defaultValue = -1
        }
    )
) { entry ->
    AboutScreen(navController, entry.arguments?.getInt("id")) // dig out the data and pass as param(s)
}
