/**
 * Guards the v1 invoice projections against silently starving the render

 * rounding" (`deduction_total ?? 0`, `ore_rounding ?? company ?? true`), so a
 * projection that drops one of its inputs does not error: it renders a PDF
 * and a locked Swish QR (editmask 0) with the WRONG amount on that surface
 * only, while the dashboard PDF and the sent email for the same invoice show
 * the deducted "Att betala". That is the exact bug shipped on the v1 pdf
 * route when INVOICE_PDF_COLUMNS predated ROT/RUT and nothing pinned it.
