I can see the settings on a Simple site. I think it's not expected? 🤔

It is not, must not have any checks for site type internally. It lives on security settings which is only available to atomic so that make sense.

We're moving this to server settings now anyway. Will revert the revert.

I thought it would be good to put it on the Monitoring tab, but I realized that it would be better to have all the settings in Server Settings, so LGTM!
