If you are set on NOT welding that repair
I would pop the door card
Clean paint back to base
And use an angled brace - I fear it will need to be relatively thick and long to offer real support.
Simply placing a piece of SS on the flat will likely lead to fatigue and cracking again
Is it possible your hinges / latches are out of alignment allowing a lot of movement ? I can’t get my head around the failure process
If as you say something was wedge in the door upper and levered the door outwards I’d expect to see buckling on the end face not cracking?
But who knows... thinking wildly could this be the result of someone levering the upper outer corner to attempt an unlocking of the door?
