fix: allow integer sentinel in set_page_position URL for Wagtail probe

Wagtail calls reverse("wagtailadmin_pages:set_page_position", args=[999999])
to test URL existence before rendering the reorder button. The <object_id:>
converter regex requires 24 hex chars, so 999999 fails. Switch to re_path
accepting both formats; the view's ORM coerces the string to ObjectId.
