SkyratBot 01348f3964 [MIRROR] psyker gang fixes [MDB IGNORE] (#18471) 
* psyker gang fixes (#72330)

## About The Pull Request
adds more ammunition, and also signing on the psyker ship
fixes some minor stuff
you can see other echolocation receivers as fully purple now, rather
than just their outline
echolocating people have night vision, to prevent bugs with them not
being able to see echolocated tiles
psyker pirates have headsets that increase their echolocation range
partially fixes the shuttle docker. need someone smarter to look at it
with me though, you can physically use it at least, just cant see yet.

## Why It's Good For The Game
they are not very playable right now

## Changelog
🆑
balance: adds more ammunition, and also signing on the psyker ship
qol: you can see other echolocation receivers as fully purple now,
