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).
