As title says, photos attached. I tried pushing the silver piston things in with a plastic tire thing, but the silver bits won’t budge at all. There’s a little clear oil of some sort around the pistons, but it’s not gushing out and there isn’t a ton.

The piston popped out.
You need to push them back evenly. As if it’s off the piston will bind. Also the piston is quite advanced, please be careful to not pop them out. It isn’t bad but would require a full bleed of the system
If you can get a screw driver all the way though the gap to the other side and apply pressure at the top and bottom of the screwdriver, you should be able to get them back.
Did you squeeze the brake lever with the wheel off? I think you might have….
1. Thoroughly clean inside there with brake cleaner.
2. Open the bleed port screw on the lever and arrange a rag there to catch any overflow.
3. Using a plastic tyre lever, gently lever the pistons back into the caliper. They are those thick circular discs that are blocking your pads from fitting.
4. Once the pistons are flush inside the caliper, reattach the bleed port screw and clean up any overflow.
5. Fit brake pads, reinstall wheel, centre rotor if you need to.
If you don’t have a pad spreader I use a Pedro’s tire lever in a pinch at the shop I work at. They are also $5 a pair at most LBS and they are great tire levers, I keep a pair in my frame bag!
push in your pistons to reset the calipers.
use your tire lever to bush the round thing all the way back. (you can clean it and grease a bit )
Pop the old pads in, flathead screwdriver and Jimmy the pistons outward into the calliper. Unless you’ve popped it right out, in which case that may not work and that’s the extent of my knowledge
