Callback pages for Auth0 Login/Logout

[cubap]

Logout

After a successful logout, a user's logged out status should be reported with a few simple links to

1. log back in
2. head "home"
3. learn about related projects (RERUM, for example)

Login

This landing page is more complicated. The state that is passed back from the Auth0 login widget will contain the referrer followed for the authorization prompt.

• No state: It should be an error if someone tries to go directly there. Something simple and visual with a link tot he homepage is appropriate.
• Signup or Login: The logged in landing page. By default, this is at least the list of user projects, similar to the 2.8 page. If there are no projects, the Interface should show the Welcome page for new users.
• Interfaces: Any other pages are quickly tested for URL validity and then redirected.

Notes

There will be a flash of content in most cases as the redirect happens, but no artificial delays should be used to pass a "Access granted" type of note.

Since redirects cannot be guaranteed correct or useful, care should be taken to find a way to eliminate any login loops, with possible interruptible options if we've seen the login for the third time in 20 seconds, for example.

state is used here, as an example https://github.com/CenterForDigitalHumanities/glossing-entries/blob/2d1c88faed252a9f55057613e8a7849230212538/js/shared.js#L142

When you want a break, @thehabes this is a cherry on top of the work you already did for auth.
