WebApplication.UseStatusCodePages() cannot handle unauthorized requests without explicit UseAuthorization() call

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

These are observations from implementing auth with Server-side rendered pages (SSR) in Blazor Preview 6 - using Razor components instead of MVC Razor pages.

Cookie auth just works, that is great. But there are some issues:

Issues:

- ``AuthorizeRouteView`` doesn't work with the router. The ``NotAuthorized`` fragment does not get rendered. Instead I get redirected to a layout-less page saying: ``Error: 401 Unauthorized``.

- The ``LoginDisplay`` doesn't re-ender when logged in using form. Redirecting to another page would help here.

Questions:
- How do I redirect to another URL from a component that server render? ``NavigationManager`` of course doesn't work here.

### Expected Behavior

When unauthorized and entering page that requires authorization,
I expect the ``NotAuthorized`` fragment to be rendered with the ``MainLayout``.
