feat(pdf): drop the prices-excl.-VAT notice from offer/order/PO PDFs

The 'Ceny jsou uvedeny bez DPH...' explanatory line is removed at user request from all three non-tax-document PDFs - the 'Celkem bez DPH' total label carries the information by itself. Dead vat_notice keys and .vat-note CSS removed; tests now pin the notice's ABSENCE (file renamed pdf-vat-note -> pdf-no-vat).
