To test the restricted routing when filling up required fields, we fill up the field and then navigate to the root path and checking that we're not redirected.
This is somewhat flaky, and the screenshot shows we are back at the profile page, without any prompt to fill up fields.
My hypothesis is in cases where the backend is "slow" to respond, we're navigating away from the page before the request finishes (which will redirect back to the profile page.)
This PR adds an expectation after saving, to wait until the unrestricted profile page is rendered, before navigating away.
If a user has a required action, e.g. adding a 2FA method or filling in new required fields, we disable client-side routing except to allowed pages.
This led to a situation where a user might navigate away from e.g. the profile page to look at the new ToS, and then being "stuck" due to not knowing how to get back to accept the new terms.
This PR makes it so that if you click any restricted link, instead of doing nothing we transition the user back to the page where they can take the required action.
We want to allow admins to make new required fields apply to existing users. In order for this to work we need to have a way to make those users fill up the fields on their next page load. This is very similar to how adding a 2FA requirement post-fact works. Users will be redirected to a page where they can fill up the remaining required fields, and until they do that they won't be able to do anything else.
