clickable alerts glow + the slimed status effect now actually tells you how to get it off without water in the description (#87902)

## About The Pull Request

 clickable alerts glow (regex: /atom/movable/screen/alert/.*/Click)

## Why It's Good For The Game

people are much more likely to look at the chat or anywhere else than
the status effect (really, its usually never worth reading 99% of them
so they end up ignored)

## Changelog
🆑
qol: alerts that do stuff when clicked glow gold
