In third photo there is some sort of flange/washer/nut on back surface of pad holder and it is hanging up on the thick washer of the eyebolt. Move the post in towards the rim one millimeter and alignment will immediately improve by five degrees. The thick washer can be filed with a small round file. File a groove at an angle and the pad post can be at any angle you wish without bending anything. That is why that washer is there and that is why it is thick. Also the straddle cable is way too long.

There are enough small problems here to disqualify the owner of this bike from being his own mechanic. DIY is like a religion, time to leave that church before an accident occurs. Many riders will do 99% of braking with rear brake only, it remains that the front brake is the powerful one. No front brake, no safety.

The story about bending the brazed post is terrifying. No way to know if that post is still safe except a hands on inspection by a mechanic. Preferably an employed mechanic with general liability insurance. The post might be fine. It might be possible to add some brass or the post could be re-brazed. With no inspection but by photo and observers far away the safe plan is a new fork.
