[Fix] Add permission check to SF Search in cheat mode

[JustAHuman-xD]

Description

In the unlikely event someone manages to get a cheat sheet they can cheat in items with the search feature, we don’t want that.

Proposed changes

Change the logic for search items to match the logic for normal items when clicked. (Have a permission check for cheating, cheat in stack when shifting)
