I think this was an unfortunate event and there seems to be fault on both parties. It seems that your neighbor is remorseful. I would not want you to take advantage of this persons remorse by asking for the price of another puppy. You mentioned that your pup was a rescue and that it had significant income potential as a breeder. This sounds like youre looking for money. It may not be intended but that's how it reads. As the neighbor it seems decent that they took you to the vet and that they are willing to reimburse you for 1/2 of the vet bills seems fair. I do not feel that she is obligated to pay you full vet fees because the incident is your fault also since you lost control of your dog just as she did.
