QuickBooks Online: invoice Balance is read-only, update the lines instead

When a QuickBooks invoice update succeeds but the balance stays put, check what you wrote. Balance is read-only; the API ignores writes to it without erroring. To change what the customer owes, update the invoice line items (amounts, rates, quantities) instead. The balance recalculates from the lines.
