Drop builder and alarm for update Confirmed Payment transaction
  Update Payment state gadget (JIO)
  Generate the link from the Sale Invoice Transaction rather them Payment (since they might not exist)
  crm: Update from Unpaid Payments to Unpaid Invoices
  Now we rely on lettered/non lettered invoices rather than payments.

   The usage of Entity_createPaymentTransaction is slightly faster since it is used to create the payment before the redirect.

   Since we arent creating Payments globally, call the builder to
produce a single payment would be overkill.

   isLettered is more accurated to accounting terms and easy to understand.

   The Payment Transaction should be created once the user attempt to pay, and not on every Payment Transaction.

    The implementation shouldn't rely on the existence of Payment Transaction for knowing if the Sale Invoice Transaction is payed or not.
