Front-end (fis.inv_shared.js / fis.inv_txt_de.js, rebuilt bundles): - 3-way set display switch (setprice/itemprices/setonly) via admin.setmode, emitted into InvoiceOptions by FdsInvoiceData.BuildInvoiceOptions. - Each request block now posts items[] in the backend contract shape (title/desc/qty/price_net/total_net + set type/setId tags) via itemToContract. - invcPayload normalises the editor model to the field names BuildInvoiceParams reads (sms totals -> new.total_net/total_gross, invoicetitle->title, loc->provisionlocation, admin.paymentterms->new.paymentterm, CustomerId->customerid). Back-end: - BuildInvoiceOptions adds the setmode token alongside §13b. - VAT rate+amount now taken from sms.vat (HighestVat) instead of the broken items 'is List<object>' detection that pinned the rate to 19. - InvoiceSetPricing blanks price/total cells for text/title heading lines. Tests: set-pricing text-line blanking, HighestVat selection/parsing, updated the VAT param test to the sms.vat contract. 180 passing. Note: the second VAT slot (InvoiceVAT_2) stays unused by design; mixed-rate invoices store only the highest rate (pre-existing, accepted). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
