Engineering guidebook megaupdate v2 (#33062)

Significantly updates the Engineering guidebook (more explicitly the Atmos section) to have a lot more relevant and useful information.

Right now engineering has been getting update after update with no real change to the relevant guidebook entry. This has lead to a lot of out of date information and bad practices being prevalent in the guidebook, something that pains me to read.
