Nice work.

You've basically cold set the fork blades back to their original bend, and one of the nice things about steel is that small bends like this can be cold set without compromising the strength of the structure as long as it's carefully done. As long as the fork blade walls didn't get wrinkled or buckled, and the brazing between the crown and the blades shows no cracking along the crown shorelines, it should be fine. This is the kind of repair most framebuilders avoid like the plague because of potential liability.

The steerer tube reinforcement at the crown is normal butting; there is a taper between the thinner tube walls at the top of the steerer and the thicker walled butted bottom end where it's brazed into the crown.

This is pretty typical of threaded steel steerers with 1.5mm wall thickness at the top, a 30mm transition taper, and a 50mm butted section that has 2.3mm thick walls.
