Lucy 79a26d26e5 Fix some instances of trying to directly qdel lists (#90227)
## About The Pull Request

this fixes a bunch of code incorrectly calling qdel directly on a list,
and adds a stack trace to qdel if someone does pass a list to it

## Why It's Good For The Game

because I'm pretty sure qdel ends up calling fucking `del()` as `/list`
is not a `/datum`

## Changelog

No user-facing changes.

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 its arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
