peroxide is more useful when trying to clean the plant from exterior pests, and it's possibly harmful if you pour in into the soil. As it will just sit in the soil and fuck up the many biochemical mechanisms that keep the plant alive. So as of right now there isn't much you can do to help him other than laying off on the watering (see pic related for some guidance). In the future I'd heavily recommend you bake or steam the soil to sterilize it (see second pic)
As for the bonsai tree, it's probably a bit too much. It takes A LOT of work to keep them healthy and pretty. If you really wanna get into that sort of stuff I suggest starting with some more hearty and faster growing plants to really get the experience of how to prune and graft effectively. I'd personally start with an indoor rose plant, but you should do some research to see what you wanna grow and if it fits your needs. Don't get discouraged if you fail the first couple times, pruning and especially grafting are a real bitch to get right (I have yet to get a graft to succeed to this day).

yep that looks like bacterial wilt, doubt he'll survive. :/
This is quite a comfy thread, I might post my garden progress for next season. I've got lots of stuff planned so it should be interesting.
