A little architecture trick here! DTI 2020 authorizes support staff requests by means of a secret token, instead of user account stuff. And our support tools still all call DTI 2020 APIs. So here, we bridge the gap: we copy DTI 2020's support secret to this app's environment variables (I needed to update `deploy/files/production.env` and run `bin/deploy:setup` for this!), then users with the new `support_secret` flag have it added to their HTML documents in the meta tags. Then, the JS reads the meta tag. I also fixed an issue in the `deploy/setup.yml` playbook, where I had temporarily commented some stuff out to skip steps one time, and forgot to uncomment them after oops lol!
