feat(eims): printable receipt PDF with RRN and QR

eims-receipt-document.mapper.ts maps an EimsReceipt onto the shared
InvoiceDocumentModel layout, reading amounts back out of the stored request
body. Refuses to render anything not REGISTERED. GET
invoices/:id/eims/receipts/:receiptId/document, scoped to the invoice.
