Here's the motor mounting plate. The portion of the seal with the spring is installed here, and the ceramic (white) side faces this half of the seal.
This is exactly how it was on the original seal with the pump, from the factory. I just put a new seal in when I got the 1st replacement motor.
I think my wet end has it configured backwards, with the seal part with the spring mounted into the motor mounting plate.

That is backwards. The spring side goes on the impeller side and the white ceramic goes in the mounting plate. That is what is probably overloading the motor. But you probably have ruined the seal so I would replace it.

It doesn't, though. The spring side won't fit in the impeller (too big) and the ceramic side is WAY too small to go in the mounting plate.
I'm guessing this wet end is backwards compared to most others?

My mistake. Waterway evidently decided to do things differently than most pumps and flip the seal. I just assumed they were the same and I shouldn't have.
You had the seals installed correctly although you need to make sure the white ceramic seal is bottomed in the impeller. The surfaces need to be perfectly parallel when they meet. Also check the seal surfaces for any damage.

Should there be an o-ring or any sort of silicone sealant behind the spring seal?

That should have a rubber seat so it should just be clean on both sides. They do make seal lube that is designed so the seals insert easier but it is not a sealant. In fact, you want to avoid and sealant to prevent issues with the seals. Only use the lube that is designed for the seal but that should only go in the rubber parts and not the seals themselves. Those need to be kept clean of everything.
