You may be able to bend the pins back, the top pins may generally only hold the ribbon cable down (with pressure againts the bottom pins) to make contact with the cable. The plastic piece that also applies pressure is missing.
It is a bad idea to be turning the computer on that way...
You are likely shorting more than just the power switch, the LED powered circuits if you short them, may cause permanent damage to your board.
All may not be lost here, on the back side of the connector (the other side of where your aluminum foil is located), the pins there are the pins the cable connects to, you could solder the cable directly to those pins and then use the power button. Because I could not find a pinout of that connection, I do not know which pins do what. So directly soldering on the ribbon cable might be the best option just make sure you solder the cable correctly (think about the direction the ribbon cable plugs in while soldering...
Only 2 pins should be needed for the power button (those are the 2 you can short without damage to power on the computer). There are 5 pins in total, some of those likely are for LED lights, as mentioned, shorting those pins that carry current is a dead short which will cause heat and potentially damage the mainboard.
I will continue to look for a pinout.
