remove hitbox on display signs

Title. This way we can mark things without the sign getting in the way.

The sign is so small that it makes sense, Hearthling could just step over it.

Suggested plenty of times, the devs reactions to this that I recall sounded like a definitive 'no'.

My guess their reasoning is that the signs should take room so there is a trade-off between packing cupboards as dense as possible and having less of them but being able to mark what's in them.

Nevertheless, I would like to be able to hang display signs onto the doors of cupboards or a similar solution like placing signs on top of them.
