Emergency Relief Capsule (#76457)

## About The Pull Request

Getting back into coding by making some soul PRs.
Adds a new kind of bluespace capsule which replaces the default one when
the "budget pods" station trait runs, and is available from the vendor
for a (marginal) discount.

The Nanotrasen Emergency Relief Capsule provides a port in the storm for
people with an urgent need, and very little else.

## Why It's Good For The Game

This one is mostly just kind of funny I'll be honest.
I guess it uuuuuuuh provides a kind of pod with no GPS signal if you
really want to go off the grid? But anything I write here is secondary
to the point of "someone suggested it on the forums and I liked it".

## Changelog

🆑
add: Budget cuts can sometimes effect the station's supply of Emergency
Bluespace Shelters.
