feat: Moves TrunkSize to be it's own namespace rather than being under DuctSizing, as it's got it's own database model, etc.

feat: Moves rectangular size to room namespace instead of under duct sizing, since it's stored on the room database model.
feat: Uses shared duct size container for both room and trunk duct sizing containers.
