I think that your design will want to “rack” pretty easily.

If I were designing this for a customer, I think that I would use plywood panels next to the stove and wall. The wall panel would be dadoed to accept the stove panel, and they would be glued and screwed together. This will give you a rock solid corner to work with. I would also use some reflective insulation on the wall panel to minimize heating when using the oven.
