[MIRROR] Resprited assemblies (#29275)

* Resprited assemblies (#85763)

## About The Pull Request

Refreshes absolutely ancient assembly sprites in 3/4 format

![image](https://github.com/user-attachments/assets/433b25d2-b1be-423e-9423-d71067ee54b5)
Top to bottom, left to right: voice analyzer, health scanner, condenser,
igniter, proximity detector (now inspired by IRL motion detectors),
remote signaller, timer and infrared beam emitter. Timers now also show
time left with their blinking lights, additional lights will blink for
every 10 seconds remaining on the timer

## Why It's Good For The Game
Current ones are absolutely ancient and rather abstract, I am honestly
not even sure what half of them were supposed to represent.

## Changelog
