Closes:#9958

What the issue was

1. Hit app pagewithout any cookies
2. Get redirected with a 303 to/login withredirect query param set to the app url.
3. Hit the login page
4. Enter credentials
5. This code navigates you to the redirect url
6. You hit a 404 page

The technical thing to note is that step 5 is doing a react navigation. We need to send this URL in an HTTP request to the Golang backend to generate thecoder_signed_app_token cookie. The reactNavigate does not send an HTTP request to theredirectTo url.

This is also an issue with subdomain based apps. The redirect fails.

What changes

This changes all app based redirects to a window.location.href change. This triggers a new HTTP request to the redirect url which the Golang BE can return aset-cookie for the app authentication.
