ADMIN_AUTHENTICATION_TOKEN but is not immediately enforced

When opening the home page of the Terrareg instance, the content of the homepage briefly appears, before it is blocked by the required input of the admin authentication token.

The primary loading of the login page should be enforced in a way, so that nothing else finishes loading or appearing (not even through web dev console), before the login page finishes loading.

As of right now, an unauthenticated user can view the home page freely, for less than a second, when loading the homepage for the first time in the browser.
