Read receipt lines under the keys the receipt panel renders

The order-details panel reads qty/description/amount from
expense_metadata.line_items. A grocery shop is a receipt like any other, so it
stores the same keys rather than name/quantity/line_total — otherwise the rows
arrive complete and display blank, which is exactly the failure ING-8 names.
unit and category are the two fields a grocery line has and a delivery line does
not; nothing renders them yet and the category composition will.
