You aren't going to be able to change the bunny's schedule. They are going to be active during their active times and sleep when they want to.
In my experience bitter apple spray, gel etc hasn't been effective on rabbits. Your mileage may vary, but rabbits, as plant eaters eat quite a few things with a bitter taste and it doesn't bother them that much, not the way it does with cats/dogs. I also have not had luck with cayanne or other hot pepper stuff to keep them from chewing.
You could attach some sea grass mats on the inside of her hutch/enclosure for her to chew on or scratch at so she won't chew the bars, or even attach cardboard for the same purpose.
I don't keep bunnies in my bedroom because of the sleep schedule difference and because I've only ever had one rabbit that didn't pee and poop on the bed or destroy the blankets.
