Adds a new expansion card to nukie base, and buffs nukie ordnance (#90967)

## About The Pull Request

Rearranges some stuff in nukie base and adds a freezer line into the
chamber, with a electrizer for hydrogen.
Adds a pipe scrubber so nukies can clean the pipeline out faster
and adds a new keycard the janitorial closet for 10 TC coming with
neccesary janitor equipment and a water vapour canister!

## Why It's Good For The Game

Crew can already make hydrogen pretty fast and usually suicide bomb
nukies with it, this allows nukies (who think a little out of the box to
do the same with the crew, adding more setups possible with the ordnance
section and some quality of life aswell like a door letting the person
trough it
