If she was terribly malnourished in her previous home, maybe her tummy just over-reacted to all the new offerings. And you mentioned she drinks huge gulps in her bath - dehydration decreases their appetite, so if she's kept hydrated either by a daily bath or by giving her water from a dropper, her appetite should improve.
She already looks amazingly better! Phoenix/calci/reptiworms or butter worms are soft as well as being full of calcium, so those would be good options until she decides greens are worth a try.
