However, my money is still on the Blue Fairy or the sorcerer (sorceress?) being the one behind the creation of the physical book itself.
Crack theory: Blue = Sorceress (the hat is blue and covered in stars after all)
As for the alternate page 23 (which I think is a nod to D23, the “official” Disney Fan Club),
Maybe, but more likely to be a LOST reference I’d say, they love using the LOST numbers in this show and 23 is one of them.
