I went to the local bike store and they strongly threaded in an M3 bolt, but could not extract the pin by pulling on it. They tried 40 minutes. They think it's corroded or bent into the cam cylinder since wiggling the bolt when it's in the pin will turn the lever back and forth. They tried WD40 on it too.

Looking at your 1st picture, the hole seem to have some shavings. is there a bush between the pin and the frame or is it monoblock? if there is a bush, I would run a reamer in the frame to clear it as the shaving make prevent the lot to move.
