removes alot of click-related self registering signals on basic mobs (#87220)

## About The Pull Request
there was no real benefit of using signals over proc overrides for many
of these cases.

## Why It's Good For The Game
registering signals on self when we can just override the proc is
un-necessary, im responsible for most of these so im just confronting
the sins of my past
