Removes a couple of duplicate gag map_icons + fixes the gags_recolorable component + most lootpanel gags previews (#91341)

## About The Pull Request

Turns out there were a couple of black mask subtypes that I missed as
well as a prisoner uniform subtype.

Also fixes some bugs that are not related to the map icon pr to further
improve the situation with GAGS previews.

## Why It's Good For The Game

Smaller .dmis, working previews

## Changelog

🆑
fix: spraycan can now be used to recolor the gi, glow shoes, striped
dress, H.E.C.K. suit
fix: most GAGS items should now be showing up in the lootpanel again
