fix: gross discount layout for VAT-inclusive invoices

With inclusive pricing and a discount on Grand Total the Total line is
the tax-inclusive item total and the discount is printed as entered,
followed by Total After Discount, which the Net Total and charge lines
then break down. Other cases keep the net layout: Total (net before
discount), the discount's net share, Net Total, charges. Thai label for
Total After Discount.
