Engineering machinery and consoles area detection refactor (#26716)

* Gravity generator, Atmos Control Computers, and Station Alert Computers now work by area rather than Z_level

* Cameras get added to network depending on ancestor area

* Station Alert console work by area

* Adds a check so we don't get_area on a null variable

* Gravgen also checks for z level. Area check now includes some types of ruins that weren't checked

* Keeps everything on the Z level. Atmos alert computer now iterates over alarm, but still presesents area names

* Engineering monitor gets networks from the area it is placed in

* Adds missing area prototype to the prototype list

* moves the area check to a function

* reject legs, return to snek.

* Revert "reject legs, return to snek."

This reverts commit 1dfc2c4454.

* I don't know what happened with paradise.dme, but it seems ok now

* Requested style changes and remove redundant nulls

* oops

* Another empty line removed
