Try supporting your barre chords with your thumb on the back of the neck. If you press in with your thumb, it makes it easier to press the strings down. Other than that, some people use a technique of doubling up fingers on barre chords (one on top of the other) to help.
I have to say I've never heard of that happening, even among all of my friends that play ukulele. I play 2-4 hours a day as well and my fingernails have held up. I take hair skin and nail supplements though, so maybe start with that? I would buy some felt ukulele picks off of amazon too while you wait for your nail to heal. Good luck!
