Hidden Shell Records, take TWO!!! (#20713)

!!! Please merge AFTER #20723 for migrate version (this PR is set up to
seamlessly be merged after that PR) !!!

Adds a new option to character preferences determining whether a shell
is a hidden shell or not. Right now this is a Yes/No toggle that solely
makes records display as "Human" instead of "Shell Frame".

The previous iteration of this was icky.

I hope this is better.

My rationale for this is twofold:
Right now, you can only play a hidden shell "correctly" if you're
untagged. Firstly, this isn't explained anywhere, so people might miss
this by playing a tagged shell that's playing human. Someone might do
this because a tag can be a potent story tool, especially for specific
brands or lines of shells. Imagine tag scanning a runaway you've found
and getting presented with `HLTD-S07U24`, suddenly you get a huge amount
of storytelling there that wouldn't be present without the tag. <sub>any
similarities to persons living or dead is purely coincidental.</sub>

Secondly, it also means you can't play a shell who doesn't try and hide
it, but also has no tag, because that'll automatically show as human,
which is problematic in many ways.


Also, I moved the "species" field in records to the top with the rest of
the public info, and took it out of employement records, because
security and medical would definitely also get that info, logically
speaking.


In the future (with lore team approval) i would like to enable certain
human citizenships for shells with this preference enabled (likely just
Sol, but i mean if lore team wants we can get wacky with Dominia too),
but that's out of scope for this PR.
