Test certificate issuance against the staging server

Walks through the whole ACME (automatic certificate) flow against Let's Encrypt's staging environment, which has separate rate limits, so no real certificate is issued. Confirms your domain, DNS, and web server setup work before the real run. Safe to repeat as often as needed.
