Portable atmos machine circuit boards fixes [NO GBP] (#85414)

## About The Pull Request


![image](https://github.com/user-attachments/assets/8c7247c3-ecf8-4598-a5d3-8db9cbef8921)

I didn't check the examine text on the circuit boards when I was adding
them.

The pipe fitting items didn't have a proper name and the examine text
was saying "pipe", confusing players.

Also the machines remained wrenched down on construction if the frame
was wrenched.

And the fittings that people get from the RPD didn't have the correct
typepath.

## Why It's Good For The Game

Fixes #85384
Fixes #85409
Fixes #84778

## Changelog

🆑
fix: Portable atmos machine circuit boards list correct components
fix: Portable atmos machine circuit boards accept unwrenched fittings
fix: Portable atmos machines are movable on construction
