Deploy foldable (#30000)

* Deploy foldable

* Add NetworkedComponent and access to the component

* Add handled to afterinteract

* Use drop target location instead of setcoordinates

* Put back in hand after failed deploy

This prevents dropping the bed when clicking while inside a locker.

* Created BaseDeployFoldable for folding chairs, body bags, and rollerbeds
