Subject: [PATCH] feat: Fancy Screenshake from Ephemeral Space (#5503)

* cherry-pick: Screenshake (EphemeralSpace/ephemeral-space#627)

* commit your shit at some point maybe

* y

* who knows

* rename?

* debugging  + shit api

* i hope no one fucks my ass

* erm

* p

* replace with shit that makes way more sense

* stuff

* pretty sure this is just fine

* actual fix noise shit

* uhhh hmaybe if i feel like it wrong then later

* explosion shake

* grav shake

* gun shake

* idk

* projectile melee

Co-authored-by: DisposableCrewmember42 <disposablecrewmember42@proton.me>

* tweak: tune recoil on weapons

* docs: add _ES license info to LEGAL.md

* fix: screenshake on spawn fix from ss14Starlight/space-station-14#3664

Co-authored-by: neomoth <69372252+neomoth@users.noreply.github.com>

* feat: add client cvar to disable screenshake

* feat: add screenshake toggle to accessibility settings

* fix: upmerge compatibility

* docs: properly document cvar

* docs: add missing import comments
