Fixes the cooking codex searching and some duplicate entry shenanigans (#22855)

Cargo orders would have trouble clearing the list of orders shown
without reloading the ui, due to a lack of unique ID if there was
several of the same item. The same applied to the cooking codex. This is
fixed now.
This also fixes the cooking codex search.
