Add a loading state while the compenent fetches authentication info

[madeofpendletonwool]

As the app loads initially there is a small moment on some pages where you can see the login screen while it fetches login info. The better way would be to display the Pinepods loading icon instead. To implement this there needs to be a loading icon displayed on the / route (login route) until we get past the auth checks. Then show the actual login component. Doing this will fix the issue for all pages at once.
