Suggestion to have option to set Cloudflare ports for Webmin and Usermin during automated install script

… Nginx website failed! : virtualmin-nginx::feature_setup failed : virtualmin-nginx::feature_add_web_webmail_redirect failed : flush_file_lines called on non-loaded file /etc/nginx/sites-available/domain.tld.conf

@Jamie, this is clearly a nasty bug! When Edit Server Template → Website for domain has Redirect webmail.${DOM} and Redirect admin.${DOM} disabled on Nginx systems, the domain creation simply fails with the error above. I see this bug on both Debian 12 and Ubuntu 22.04.
