Resprites Catwalk Tiles to match TG's floortiles (#84819)

## About The Pull Request
Forgive me Maintainers, for I have sinned.
Months ago, a year ago, maybe longer, I PR'd some new and improved
sprites for the Catwalk Tiles here to TG. And when I did, I did not use
the right tile palettes for reference.

I have come to atone.

Additionally, I removed a duplicate white catwalk tile (flat_white - the
one left is iron_white) and changed the `none`/error icon in the file to
double as both an error marker, and a template of the catwalk mesh for
future catwalk tile sprites.
## Why It's Good For The Game
Consistent matching tile sprites are much, much nicer to look at.
