Moves the departmental delivery area check to a unit test so it stops spamming logs (#83215)

## About The Pull Request

So, thanks to the map not being loaded yet when jobs are initialized,
the logs are needlessly spammed by a check that can never pass.

Also adds some possible locations to engineering and science

As such, I just moved all this logging stuff and screaming at
mappers/coders into a unit test. I honestly only have very vague
understanding of how these work so someone with more knowledge please
check if I did everything right.
