[MIRROR] Engineering autolathe now prints engi inducers instead of science ones + boosts recharge rate of sci-printed inducers [MDB IGNORE] (#25795)

* Engineering autolathe now prints engi inducers instead of science ones + boosts recharge rate of sci-printed inducers (#80126)

## About The Pull Request

Allows engineering to print/order engi inducers instead of science ones.
They have their own type of inducer, so its weird that the amount of
them is finite.

## Why It's Good For The Game

I thought this was the case when I made my crossbow PR, and it only is
craftable with an engineering one. Turns out engineering quickly ran out
of inducers to make them with since they only get three. Oops.

As for the science inducer charge buff, around half of my 400ish hours
in ss13 is engi, and not once have I been asked by a scientist if they
could have a better inducer. 500 charge vs 1000 charge is only a change
of clicking an apc again and waiting an extra second. Plus, the reason I
picked inducers as the item that the crossbow required in the first
place is that 95% of rounds they never once moved from the closet (and
people most certainly open said closet, since the insuls are almost
always gone.)

## Changelog
🆑
qol: Engineering now can print/order engi inducers instead of science's
purple ones.
bal: Sci inducers now recharge 1000 charge per go, just like engi ones
do.
