/// This view acts as the main content router in the application, switching between
/// different feature views based on the currently selected navigation item. It coordinates
/// with the app's dependency injection container to instantiate the appropriate feature
/// view through their respective app factories.
///
/// The view handles routing for all major application features including Statuslog,
/// PURLs, Account, Auth, Now page, Webpage, Pastebin, Weblog, and some.pics.
