[browse] Rename or move should get similar treatment to delete

Renaming an existing URL has caused ghost pages to appear as our publishers are renaming pages without requesting us to delete and add a redirect for the previous version of the URL.

Since only admins have access to the redirect sheet, we'd like to limit access to the renaming feature by either option below:

- Disable the page url renaming feature for specific user group / non-admin level users

- Add a dialog box pop-up similar to the one currently in place for Delete, asking users if they have already requested a redirect and deletion of the previous page version.

Our publishers will rename urls and forget to delete + redirect old page versions, leading to the creation of lots of ghost pages we'll need to fix.

Start in the browse page URL-renaming flow and compare it with the existing Delete dialog. The issue does not name files or tests, so first locate those entry points and determine whether access restrictions or a redirect reminder is the intended direction. Done means URL renaming has one agreed safeguard that prevents publishers from leaving unmanaged previous URLs.
