Fix SAD not transferring wounds (#3167)

## About The Pull Request

Add code to `/datum/component/damage_tracker/human` to keep track of
wounds and reapply them as needed.

## Why It's Good For The Game

Fixes #3162

## Proof Of Testing

I tested with both the permanent limp quirk and breaking one of my arms
with force and both wounds stayed after using the SAD
