You are right that Saul has a right to not want people in his face and you need to be understanding of his emotions. I would avoid messing with his face at all, except when necessary. Just because you think he should think rubbing his face is pleasurable, doesn't mean he does. Many horses, abused or not, do not like us in their face. Some horses love it but others do not. That said, he does need to accept that you will handle his head when necessary, like when blanketing, bridling or brushing.
I suggest you use the technique of "advance and retreat" to desensitize the horse to having his head handled (there is an article and several Q&As on my website about this technique). First, start outside the stall where he is most comfortable, then work on it in the stall. This should take care of him being head-shy.
Also, you need to remember to be more empathetic about his emotional baggage. Your correction when he misbehaved while blanketing was more pressure than he could handle at that moment, as you obviously realized in hindsight. He has a lot of anxiety when in the stall, and for good reason. Chances are, his "misbehavior" was actually an emotional expression. While we do not want to condone a horse's disobedience, sometimes we have to understand that he is having an emotional moment and make sure that we do nothing to exacerbate his emotions. A smaller correction or a step back to let him calm down may have been more effective.
We cannot let a horse's emotions be an excuse for disobedience or manipulative behavior, but in the case of a horse that has been abused, we have to be very careful not to put him into the context of his abuse and dredge up those old emotions. I suggest you give Saul lots of space when he is in his stall and always approach him very slowly (a herd thing for us humans to do) to give him time to understand what you are asking of him.
It sounds like you have made a lot of progress with this horse; he just needs time and patience. He is lucky to have found a kind and empathetic human!
