Hologram Touchup (Init savings edition) (#74793)

## About The Pull Request

### Polishes and Reworks Holograms

Hologram generation currently involves a bunch of icon operations, which
are slow.
Not to mention a series of get flats for the human models, which is even
worse.

We lose 0.05 seconds of init to em off just the 2 RCD holograms. it
hurts man.

So instead, let's use filters and render steps to achive the same
effect.

While I'm here I'll dim the holo light and make it blue, make the
hologram and its beam emissive (so they glow), and do some fenangling
with move_hologram() (it doesn't clear the hologram off failure anymore,
instead relying on callers to do that) to ensure holocalls can't be
accidentially ended by moving out of the area.

Ah and I added RESET_ALPHA to the emissive appearance flags, cause the
alpha does override and fuck with color rendering, which ends up looking
dumb. If we're gonna support this stuff it should be first class not
accidential.

### Makes Static Not Shit

While I'm here (since holograms see static) lets ensure the static plane
is always visible if you're seeing through an ai eye.

The old solution was limited to applying it to JUST ais, which isn't
satisfactory for this sort of thing and missed a LOT of cases (I didn't
really get how ai eyes worked before I'ma be honest)

I'm adding a signal off the hud for it detecting a change in its eye
here.
This is semi redundant, but avoids unneeded dupe work, so I'm ok with
it.

The pipeline here is less sane then I'd like, but it works and that's
enough

## Why It's Good For The Game

More pretty, better ux, **static works**

## Changelog
🆑
add: Holograms glow now, pokes at the lighting for holocalls in general
a bit to make em nicer.
qol: You can no longer accidentally end a holocall (as a non ai) by
leaving the area. Felt like garbage
fix: Fixes static rendering improperly if viewed by a non ai
