Makes the floors in the CI room indestructable (#96909)

## About The Pull Request

Switches the floors in the CI room to be indestructible. They're not,

## Why It's Good For The Game

The walls are indestructible and not the floors. I feel like these
should be indestructible too.

## Changelog

not player facing
