Fixes the rest of the sleeps in Life() (tgstation#86601)

## About The Pull Request

Life should not be intentionally sleeping that is dumb

Most of these are trivial, hierophant needed a bit of jigging but it was
fine

Also adds SHOULD_NOT_SLEEP(TRUE) to life after talkin with the other
maints

## Why It's Good For The Game

No excuses for feature coders
