Makes easy_random_mutate mutated genes researchable (#95717)

## About The Pull Request

sets the scrambled flag of easy_random_mutate to FALSE

## Why It's Good For The Game

Within my extensive geneticist playtime I have many times rushed the
avalible genome in a round by myself, having a somewhat fast time of
about 30 min, almost not exiting my lab in a non-stop A-T C-G frenzy. A
kind of painful process for a human hand because of the amounts of
clicking involved and our increasing number of avalible mutations, so i
came up with what i hope is an adequate solution. In the practice what
this pr does is allow for the random mutations caused by
easy_random_mutate, which if im not mistaken are:

toxin_reagents.dm | Unstable Mutagen 
body.dm | Unstable DNA mutation 
radiation_storm.dm | Radiation storm weather effects
floral.dm | Plant-mutating radiation projectiles
experimental_cloner_fuckup.dm  | Cloner malfunctions
eldritch_painting.dm | Heretic eldritch painting examines
_species.dm | Species radiation damage handling

to be saved to the dna consoles. under normal circumstances it means
that unstable mutagen (and i guess cloner malf mutations) can be saved
to dna consoles. IF im not mistaken and didnt miss anything, it
essentially means that geneticists can now cooperate with chemistry in
order to achieve a somewhat less click intensive, not necessarily much
faster decoding process of the genome, at the cost of cooperating with
your local chemist, and shorter lived test subjects (since it deals tox
damage while metabolizing). because of how unstable mutagen works, this
mostly means only unlocking negative mutations, since positives have a
2% of being unlocked and noted be mutagen only works first entering the
mob, not while metabolizing.
