Brings back clean toolbox force (#91641)

## About The Pull Request

Returns clean toolbox back to their original force upgrade of 1TC = 1
damage, rather than .5 - which was added because progtots had access to
'infinite' TC.

## Why It's Good For The Game

Progression traitor is dead

## Changelog

🆑
balance: Assistant-only clean toolbox now does 1 damage per TC again.
