Subject: [PATCH] Fix PHP-FPM path mismatch in shared httpd vhost template

The shared httpd serves files from /mnt/users/{user}/{domain}/public_html
but PHP-FPM containers have them at /home/{user}/public_html. When Apache
proxied PHP requests via fcgi, SCRIPT_FILENAME pointed to the Apache path
which doesn't exist inside the FPM container, causing "File not found".

Added ProxyFCGISetEnvIf to rewrite SCRIPT_FILENAME from the shared httpd
path to the FPM container path before proxying the request.
