[MIRROR] Fix psyker echolocation lag (#1472) (#2443)

* Fix psyker echolocation lag (#82005)

## About The Pull Request
Fixes a slowly increasing lag for psykers, subtly introduced by #80042
Turns out the code expects all of the images to fully fade out before
any new images start fading in, thus the expiry time + fade out time
must not exceed the cooldown time.

Note that this will still be laggier than if you're NOT a psyker because
of how things are rendered, but it should stay consistent.
Fixes #81446
Fixes #80442
Fixes #80798
## Why It's Good For The Game
letting literally thousands of images build up on the client is not a
good thing, turns out.
## Changelog
:cl:
fix: Psyker vision no longer causes infinitely worsening lag

* Fix psyker echolocation lag
