SkyratBot 0938c796a8 [MIRROR] Adds a signal to buying items from the uplink (& fixes TC misinfo) (#26449)
* Adds a signal to buying items from the uplink (& fixes TC misinfo) (#81372)

## About The Pull Request

Adds a signal when someone buys an item from the uplink and removes
single-letter vars from the ``spawn_item`` proc, and adds/standardizes
add/removing of telecrystals from uplinks (and admin setting how much TC
they have) to ensure the UI always has the right amount of telecrystals
displayed in it.

## Why It's Good For The Game

There are reasons why someone would want to hook up to a traitor's
uplink and listen to items they purchase to do any special effect
on-purchase, so this adds support to do anything in the future with it.
Also tells players how much TC they actually have without forcing them
to close/reopen the UI every time they insert some TC in it by hand.

## Changelog

🆑
fix: Uplinks now update their UI when you add telecrystals in them, so
you don't need to close and reopen it.

Datum Component System (DCS)

Concept

Loosely adapted from /vg/. This is an entity component system for adding behaviours to datums when inheritance doesn't quite cut it. By using signals and events instead of direct inheritance, you can inject behaviours without hacky overloads. It requires a different method of thinking, but is not hard to use correctly. If a behaviour can have application across more than one thing. Make it generic, make it a component. Atom/mob/obj event? Give it a signal, and forward it's arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
