Title: LPS-30833 Cannot add subpages to a site page that is linked to a site template

Deleting the page in the site template would cause the deletion of any custom subpages of the page in the site when changes are propagated. To prevent this issue, the operation is possible only if the link between the site and the site template is not enabled.
