debug proc for visuallizing spatial grids (#92325)

Browse Source 
## About The Pull Request
debug PROC (because its super laggy so i locked it behind a proc call on
a subsystem) for painting the world based on the cell its located in

pulled out of my port of spatial grids in
https://github.com/shiptest-ss13/Shiptest/pull/4399


https://github.com/user-attachments/assets/07008518-e418-442b-ab80-6557e936fee2
## Why It's Good For The Game
useful for debugging spatial grid issues. also helped ,e discover a bug
since it calls get_cell on every atom.
## Changelog
🆑
code: debug proc for painting the world based on spatial grid.
