suns armor oversight fixes (#2713)

## About The Pull Request

One line change to make the Peacekeeper Visor and the Gilded one have
bulletproof helmet stats, as their armor inherits bulletproof vest

Also all SUNS armor now covers arms and legs too (because they're all
coats)

## Why It's Good For The Game

Less inconsistencies between intended design of item and actual
function.

Also I'm still malding.

## Changelog

:cl:
balance: Peacekeeper visors have real armor now (especially against
bullet)
balance: SUNS armored coats now cover all body parts instead of just
chest
