Blazor WASM: Catch explicit navigation to authentication/login-callback and redirect to login

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

Some of our end-users explicitly navigate to the `/authentication/login-callback` path of our site and end up stuck in the `CompletingLoggingIn` segment of `RemoteAuthenticatorView` and get the impression the site is "not working". Is there a way to capture an explicit navigation to `/authentication/login-callback` and differentiate it from a programmatic redirect after the user has entered their login details?
