Streamlines Life() a little (#96215)

## About The Pull Request

Main changes

- `handle_mutations` is gone, DNA Injectors are now managed via a status
effect
- `handle_diseases` is gone, disease stages are just handled via life
signal
- `handle_bodyparts` is gone, it was unused and in the future any
implementations should use a life signal
- `spec_life` is gone, the main content of it is now in `human/Life`,
most children implementations now use life signal, zombie tongues now
handle zombie groans
- Life signal was split in two (pre and active)

Other changes

- DNA injector code was cleaned up considerably
- HARS now alerts admins when you inject someone else with it like
Monkey
- `COPY_DNA_SE` is no longer mistakenly unused (meaning stuff like
transformation sting no longer copies "active mutations")

## Why It's Good For The Game

Across the course of a full round we spend the same amount of time doing
literally nothing in life as we spend on handling human breathing.

Now in the context of a full round this is 8 seconds. Which in the grand
scheme of things, not a whole lot, but if we can get a tiny performance
gain from... not doing literally nothing (especially when we can do
these things cleaner with signals) that's a win in my book

## Changelog

🆑 Melbert
refactor: Refactored dna injectors (both the ones that change appearance
and activate mutations), report any oddities with them like failing to
revert your appearance or mutations not applying correctly
code: Ever so slightly changed how diseases tick, report any oddities
code: Ever so slightly changed how some species mechanics tick, like
golems and slimes, report any oddities
code: The code behind printing appearance modifying dna injectors from
genetics has changed, report any oddities
code: Some backend transformation sting code changed slightly, report
any oddities
code: Zombie "idle" groaning is now tied to the tongue rather than the
species itself
admin: Force-injecting someone with HARS give an admin alert, the same
as force-injecting someone with Monkey
fix: Several methods of copying DNA (including transformation sting)
mistakenly copied "active mutations", this has been fixed
