It is rumored that no one know why planet rainbow get ruined I agree: odds are, Mao does come from Planet Rainbow! Its mention in her debut episode can't be a coincidence. Plus, the spoiler shows Cure Cosmo with a rainbow-colored skirt.

Maybe the reason that Blue Cat is a phantom thief is because the people (likely the Notraiders) who stole the life from her planet never got punished, so she feels that she should have the right to steal from people, too. If it was the Notraiders who destroyed her planet, it could explain how she knows Aiwarn.
