Forces gases to obey certain laws of nature (#35277)

* - Fixes most gas reactions deleting more gas than exists and thus making gas out of nowhere.
- Makes Noblium formation no longer multiplicative.
- Expunges invocation of a byond bug by stimulum production.

* - Redundant parenthesis
- I'm going back to sleep

* - Sends fire and fusion to jail

* - Deletes redundant line in lung code
- Adds garbage_collect and clamp to cryocells
- Adds clamp to collectors

* - Reverted the tritium burn changes because apparently I'm dumb

* - FUCK

* - Fixes division by zero when fusion has no impurities

* - Adds extra commentary for the next unlucky sod
- Compresses lines for performance or so they say
- Adds ..() to rad_act on turfs
