Test Auth Grove (login.nasqueron.org)

Summary:
The login application contains a /status route returning a 200 "ALIVE"
to ease monitoring since c494df36.

Basic homepage http/https redirections can be tested too:

• nginx redirects traffic from http to https with a 301 code
• the app redirects / to /auth/login when user isn't logged in with a 302 code

Finally, during development and deployment, we noticed URL issues.
We so test the homepage offers links to expected URL, and not
http://localhost or something else.

Test Plan: Run tests
