Important: #99044 - Ensure auto-created redirect are stored on connected site root
See forge#99044
Description
Long time ago, automatically created redirects were created on the top root page
pid=0, which has been changed meanwhile to create them
using the page ID of the changed page as
pid with forge#91776.
This led to some issues, like permissions during copying and pasting pages.
Automatically created redirects are now stored using the root page ID of the
site configurations as
pid to minimize side-effect issues and prepare
follow-up features.
