[MERGED PR] Merges mechanics with engineer

[Ikea]

I agree that 8 is a large number (Id personally be more comfortable with 7), main reason its so high is because with these pops and no pop scaling I do not feel comfortable significantly reducing the job counts as I dont want even more staffies. I do agree that theres not enough equipment for 8 engineers in storage, but my preferred fix for that is spawn engineers with a decent amount of baseline equipment that way there's natural item scaling, though that change is outside of scope for this pr. I think remapping some of the stations to more integrate mechanics with engineering would be neat if this pr went through, however ultimately I dont consider it to be an urgent thing, Im more then willing to do these map changes.
