If I've missed something that's already been covered, I'm sorry, but:
Your problem may be more related to your hand, wrist, and arm position more than your thumb or the thumb joint. For example, you may successfully concentrate on getting the thumb "angle" correct, but your remaining fingers, your wrist, and your arm may be getting in your way more than anything else and causing the numbness.
Do you feel stress in other fingers, wrist, or arm? The photos suggest to me that there is a lot of tension in your fingers and that your wrist is "scrunched up" and not in line with your fingers.
Can you provide photos showing wider views of your hand, wrist, and arm position?
Also, I don't think register key design should be considered until you're sure that you have some sort of large physical problem. I own clarinets with "normal" as well as "ergonomic" register key designs, and the difference playing the two is not great as long as the touch area is not wildly out of adjustment in relation to the thumb ring.
