Fix “Served over HTTPS” on nginx

Install a TLS certificate (free via Let's Encrypt) and redirect all http:// traffic to https://.

server {
  listen 80;
  server_name _;
  return 301 https://$host$request_uri;
}

Verify the fix

Re-run the Served over HTTPS check after deploying. Test config changes in staging first and keep a rollback: a wrong header can break a site faster than a missing one.
