Improve internal linking experience

When someone types "/" in the URL field, show a dropdown menu of available pages users can select from. This means they won't need to remember or type out the full URL path, they can just pick from the list.


Start by locating the URL field in the authoring interface and reviewing how its current value is entered and how available pages are sourced. Verify the slash trigger, selectable page list, and insertion of the chosen path in the field, using the attached image as the expected interaction reference.
