The create-screen "print" action used a separate browser-rendered HTML
template while ZIP exports used a PDFKit-rendered PDF, so the two looked
different. Extract the ZIP export's PDF rendering into a shared
renderInvoicePdf function, add a POST /api/invoices/pdf endpoint that
renders the current editor form data through it, and have the print
button download that PDF instead of opening a print window with the old
HTML template.
