I don't know if she was testing you as much as just trying to keep you away so she could do what she wants regardless of how it inconveniences you. I wouldn't send her a thank you text either, just let it be. Your W and her mom can figure this out on their own, and you don't have to stay away from your own home to accommodate it either. No need to forward her the itinerary either, your W is not keeping you aware of her actions, right?
You should feel good about standing up for yourself in a positive way.
