fix: receipt total now uses actual payment amount from DB

Browse source 
Instead of recalculating the grand total from line items + rates (which
can drift by a penny due to floating point), use the actual PaymentFromCreditCard
or PaymentPaidInCash values from the Payments table. This ensures the receipt
always matches what the customer was actually charged.
