Readds Triple AI Station Trait (#6004)

## About The Pull Request

[Originally this feature was reverted on tg as the commit it was apart
of outright deleted the secret's panel button to enable triple ai.
](https://github.com/tgstation/tgstation/commit/45ca1717d08aa591ebf3c201a56f569b00a9c71a#diff-b1ea40f4f23c37ede32062176eabbf77eca87b8478ea58764b1d2c6bc7bfc9d7)
(side note: even before the removal, the trait was set to 0 weight by
skyrat, so it'd never roll) This readds the feature while trying to not
conflict with the admin panel button. Modular of course.

## Why It's Good For The Game

Ai needs more toys and love. It is so rare you'll see a second ai on
Bubber let alone a third as sop and lack of enthusiastic/trusting
command makes it a nightmare to build one without being an antag.

## Proof Of Testing
If the station trait rolls, the admin panel option reacts accordingly.
Does not crash as far as I've tested!
