Approve closing port 22

When an app is about to deploy, Fodide asks to close the server's SSH port (22) to the internet. A Server change (careful) card appears. Make sure you know where the provider console is (step 4), tap Approve, then Yes, do it.

Why: on a test server, 24,996 failed login attempts were counted in one day on port 22. After this, SSH is reachable only through your Cloudflare tunnel, gated by a firewall rule. A guard on the server reopens the port by itself if the new way in does not work.
