Wrench pda fix (#71528)

## About The Pull Request

Fixes #71514 
Now when PDA's are deconstructed, the ID, PAI, computer disk, and
battery cell (if there are any inside) will all drop to the floor.
PDA's and modular computers that are destroyed have their behaviours
unchanged, this is only for deconstruction.
Also gives deconstructing a screentip and sets it to
wrench_act_secondary

## Why It's Good For The Game

oversight, screentips are good even if its for something you probably
wont do

## Changelog

qol: pdas have a wrench deconstruct screentip
fix: wrenching a pda no longer destroys all contents inside
