[MIRROR] Fixes sec computers having infinite distance (#1473) (#2439)

* Fixes sec computers having infinite distance (#82016)

## About The Pull Request

Camera consoles no longer have infinite range, which was caused by the
``can_perform_action`` check causing an early return before
``try_update_ui`` could run and update your visibility on the console.

This has been a bug for a long time and I've constantly procrastinated
on fixing it but it was brought up when discussing Human AI bugs so I
went in to look around and found out what caused it, so I can finally
say I did it.

## Why It's Good For The Game

Security cameras no longer have infinite range.
