Make a craftable version of the radio jammers, and make the traitor radio jammer cost 1 TC instead of 5 (#89829)

## About The Pull Request
Makes makeshift radio jammers craftable with:
1. Universal scanner
2. Headset encryption key (it doesn't steal the one from your headset
don't worry)
3. Cable coil

Makeshift radio jammers are the same as Syndicate ones, except with a
smaller active range (12 -> 5) and smaller disruptor range (7 -> 3)

Lowers the cost of radio jammers from 5 TC to 1 TC.

## Why It's Good For The Game

This is intended as a potentially overkill solution to the problem of
people shouting that they are being killed right away. Common is not
going away, but we need to do something to aide this style of gameplay
over going loud etc. By making radio jammers craftable, we allow all
antagonists to use this instead of just traitors.

## Changelog
🆑
add: You can now craft radio jammers.
balance: Radio jammers have had their cost lowered from 5 TC to 1 TC.
