fixes the museum cafeteria puzzle and some other things related to the museum (#88287)

## About The Pull Request

the dotted color board was missing a color for the 10th digit, and
orange and brown were not valid byond colors (damn you ghommie)
fake scrubbers and vents use the correct layer and plane
you may no longer deconstruct indestructible windows
you can no longer push indestructible grilles and robust windows if you
have a strong move force

step teleporters may not teleport abstract objects or mirage holders
(due to init shenanigans this sometimes teleported a mirage holder
messing the visuals up)

## Why It's Good For The Game

bug bad also i didnt make these bugs ok

## Changelog
🆑
fix: fixed the museum password puzzle (to the cafeteria), and the
scrubbers and vents there now look correctly (also fixed a rare visual
bug)
fix: it is now harder to bypass indestructible windows and grilles
(those are placed there for a reason, you know!)
