Pretty much just what everyone else said: this isn't your business, you need to stay out of it.
I know it's hard for you to watch your friend go through what you did, but didn't you come away a smarter person for it? If she gets a good old horse, great! If she doesn't, and things go downhill, as wild spot said, wait for her to get in that terrible-feeling state of mind where she's ready to admit she's wrong, and go from there.
If right off the bat you notice some of the most basic (but only essential, that it would die without) needs are being neglected, maybe offer her a few pointers, or if she won't listen, tell her parents. You don't want to immediately go over and be: "You're not doing this right." "You have to do this." "Here, let me do it." Unless it affects the total well-being of the horse, I honestly would just leave her alone. She'll figure it out in time.
And you seem so focused on her "ruining" the horse. Maddie, if you have a horse with decent training, it's really hard to ruin it...at least from personal experience. Logically Tango should be a bucker, a rearer, a bolter after all the things I've done to her simply learning, and though she has a huge go button, she's never hurt me or acted irrationally, and she's still a total sweetheart. And guess what? She only had a year of training under her belt when I got her.
