In that first picture you posted, it looked like the fender was off center not the wheel. Notice how close the left side of the fender is to the tire compared to the right side? The wheel looks nicely centered.
The forks are put together in a jig then soldered/ brazed up so everything is nice and square. I can see just a little inward offset on the right drop out and I doubt this should be an issue, it is just where the drop out settled in before being soldered/ brazed together.
