Emergency suit acid survival time buff + awareness posters

[Kubius]

[FEAT][BALANCE]

About the PR

Performs the following changes relating to emergency suits' function on Nadir:

• Doubles emergency suits' acid survival time from the default 90 seconds to 3 minutes. For contrast, proper dive suits offer 8 minutes.
• Introduced a "KEEP IT OR MELT" poster for Nadir emergency suit awareness, and introduced it to several locations on-site; one poster is placed near each arm of arrival and escape docks, and an additional poster has been placed outside Robotics and in the hall north of QM.

Why's this needed?

Emergency suits are the primary countermeasure for the average crew member to survive acid breaches, and 90 seconds often ends up being too little time to do anything of value due to their slowdown; 3 minutes offers a larger window, but still thoroughly small enough to encourage obtaining a proper dive suit if you can.

The included posters should increase awareness of Nadir's guaranteed emergency suits.

I think the map changes may have borked. Drafting to check.
