Adds Cardboard Boxes To Squad Rooms (#5930)

# About the pull request

Adds some cardboard boxes to the squad prep rooms. 

# Explain why it's good for the game

Small quality of life boon for proactive Marines wishing to make ammo
boxes for the FOB, frontline or personal use.

Adds four stacks of boxes inside the squad prep areas. Each stack
contains 10 units, though the Bravo one has 30.

No balance implications as boxes are free to make from empty shotgun
shell boxes.
