Support bluesky deep links

[tunjid]

The navigation routes in the app are mapped to the same ones used in the official bluesky web app.

However, the app expects Dids for profile ids in the routes, whereas web links use uris. This means navigation destinations will need to figure outif path params are handles or dids before proceeding with business logic.

In other words, validate route path arguments with the UriLookup class and its API before proceeding.
