Oldstation (Charlie) experiments tweaks [NO GBP] (#84379)

## About The Pull Request

There was a feedback that the new techweb made it harder to do science
on ghost roles, namely Charlie station crew.

This PR makes a few tweaks to oldstation to lower the bar on the
experiments:

- Added a pure N2O tank for easier BZ creation
- Added one diamond to the ai sat to create artificial BS crystal
- Added research console to ai sat with frontier app pre-installed
- Added a gas compressor to Beta station atmos area

Also moved the NTNet relay back to tcomms node as it requires tcomms
parts. And moved chem pack/blood pack from tier 1 to tier 0 per players`
request.

Also fixed the dissection experiments giving the old amount of bonus
points, before the recent point denomination.

Made a few other minor changes to the map.

## Why It's Good For The Game

Charlie is supposed to be friendly for the beginner players, yet the new
experiments are hard to do with the limited resources on Charlie.

## Changelog
