Centcom/Nukie mechs receive better innate armor but cannot be upgraded (#83580)

## About The Pull Request

QoL for antag mechs: no longer are you expected to sit around station
Robotics with a [materials] [inducer] [experiment scanner] to upgrade
your antag mechs, they are now appropriately armoured out of the box!
Unfortunately, this high end armour cannot accept third party upgrade
modules.

Also good because of incoming (hopefully) sprite upgrades, maulers
should become more attractive to buy.
Inspired by maplestation..

## Why It's Good For The Game

Antags like Centcom or Syndicates don't have no time to sit around in
the station robotics bay trying to upgrade their mechs - and it's insane
to expect them to do so. This is especially poor for newer players who
aren't aware of mech mechanics - such as a basic chainsaw or fireaxe
dealing 15 or over damage to their mech when a upgraded Durand isn't
affected by this.

Makes antag/centcom mechs good 'against most threats' out of the box, so
better for newbies and less stressful for experienced players who won't
have to literally _do station jobs_ to get a good mech. Did you know:
mech mechanics aren't even explained at all in-game?

Balance wise, it's "good against everything" and loses the ability to be
super-specialized against a single thing, while retaining
higher-then-normal grades on everything else. Station mechs still have
the ability to specialize in one armor, say, melee, but have much worse
grades on bullet/laser/EMP, and often have less health. Previously, a
trip to Robotics could get a D-GYGAX up to 85% melee while still
retaining 40%/50% of bullet/laser which imo is a biit *too* good. The
difference between say - 70% and 85% is fairly significant - 9 damage /
13.5 damage for 70% melee vs 4.5 / 6.7 damage for 85%, so twice as good.

NOTE: Some of the mechs receive better bomb/energy armors, which weren't
affected by armor upgrades.

## Changelog

🆑
balance: Antag/Centcom mechs now have top notch un-upgradeable armor out
of the box. You can't add armor to centcom or nukie mechs anymore, but
their default armor rating is a lot higher.
