broken Campagnolo Gran Turismo?

I had a flat in my rear tire, so took off the wheel and replaced the inner tube, I kept fiddling with the bike a bunch of times though because I installed it in correctly, so had to take the back wheel off and put it back on a few times, I noticed though that my derailleur is messed up and is all the way into the gears! did I break it or do I have the wheel installed incorrectly? I attached a couple of pictures, and one off of the internet showing how the derailleur should be!

Why not take it off the bike and overhaul it? It would be much easier to make sure everything's working properly. And you can polish it up a little bit.

I suspect that the upper pivot spring is either disengaged or broken. If that is the case, consider replacing the derailleur.

Having a hard time visualizing just how a wheel is “installed incorrectly” but I suppose that the derailer (I’m not French) could have been damaged in the process. Is it safe to assume that everything was in working order prior to fixing the flat tire? While replacing the derailer with a new one is likely the best course of action in this case, I personally, would take a whack at rebuilding it! I’m pretty sure there’s a YouTube video on how to do it .

I uploaded a video here
I'm absolutely positive it wasn't like this before I fiddled with the wheel, even though the bike still runs and shifts between the two smallest gears, it cannot make any further shifts because the derailieur is physically obstructed by the freewheel

As already mentioned, I vote for checking the hanger mount pivot spring first. They do break occasionally or maybe just became disengaged during the extra movement used to mount the wheel. Old parts eventually get tired and give up sometimes. I'm no Campy expert but I would guess you could find a replacement spring somewhere if it's broken.
