[TASK] Process _PATH_ field also in directory listing

In #87974 the special _PATH_ field was added to
FileList, to be displayed on the search result view.

To be consistent, this special field is now also
processed on building the directory listing, while
it currently has no visual effect, since the _PATH_
field is only dynamically added to in a search
context.

Resolves: #94505
