[MIRROR] Buffs implanted mining organs [MDB IGNORE] (#18059)

* Buffs implanted mining organs (#71863)

## About The Pull Request

In [70546](https://github.com/tgstation/tgstation/pull/70546) I added
some new implantable organs to mining creatures which didn't drop
anything on death.
I didn't really want these to make miners way better at station PvP so I
gave them some pretty hefty downsides.
I went too far and this meant nobody would ever implant one of them
ever, which sort of negates the point of adding it.

The implanted Brimdust Sac has now been redesigned.
It no longer sets you on fire if activated on the station, nor does it
explode if you catch fire.
Instead, if you're in an unpressurised environment (like space or
Lavaland) it will add one stack of the buff every 30 seconds
automatically.
The buff still does reduced damage on the station _and_ hurts you as
much as it hurts anyone else. In addition, instead of catching fire, you
will be slowed for four seconds.

Additionally I cut the cooldown for both organs in half because there
wasn't really any reason for it to be that long.

## Why It's Good For The Game

Encourages miners to go interact with medbay in between delivering ore,
while they're waiting for their shit to get posted.
Now when someone indignantly posts "When was the last time there was a
mining _buff_" in #coding-general you can link them to this PR.

## Changelog

🆑
balance: Rush Gland and Brimdust Sac can be used more frequently when
implanted.
balance: An implanted Brimdust Sac will stack the buff on you
automatically while on lavaland. Triggering the buff on the station will
make you walk slower for a short duration.
balance: Implanted Bimrdust Sacs no longer set you on fire, nor do they
explode if you catch fire.
