Looks to be moisture from above to me. The water heater is a sealed and insulated unit that looks dry and mold free on its bottom area, that we can see anyway. Water can and will enter at any exterior penetration like marker lights, vents, windows, etc. and also can travel along framing members until able to run downwards. I'd start by cleaning and resealing every exterior penetration.

the only issue I see with "from above" is the mold stops at the hight of the seat cushions. it makes me think there was some sort of high humidity/storage type thing going on.. or direct moisture under the seat. but ya it could have been leaking down the inside of the wall and just coming out at the bottom.
