Radiation Refactor (#19270)

* Part 1

* WIP

* The rest of these

* More stuff

* Whoops, did that wrong

* typo

* gweeen

* This all works

* SHOWER

* Rads

* awa

* rad

* Update life.dm

* edits

* Makes lvl 3 rads give you a warning.

You should already know by this point, but this makes it EXTRA clear you're getting fucked

* Update vorestation.dme

* aaa

* propagate

* gwah

* more fixes

* AAA

* Update radiation.dm

* Update radiation.dm

* mobs rads

* rads

* fix this

* Update _reagents.dm

* these

* Get rid of these

* rad

* Update config.txt

* fixed

* Update radiation_effects.dm
