orders: badge the annual summary receipts (board 211)

Migration 033 adds entity_orders.summarises_period; order_spend drops those
rows and order_feed keeps them. Unbadged, a $2,376 annual tax receipt
restating twelve monthly donations renders as the largest single purchase of
the year, so both surfaces say what it is:

- /orders  — a "year summary" chip beside the auth badges
- /orders/<key> — a banner in the same shape as the settled-rail one, saying
  the monthly debits are in the ledger under their own dates

The amount is deliberately still shown. It is the year's giving total and the
reason the row is worth keeping; it just belongs to no total on the page. The
detail page already falls back to o.order_total when order_spend has no row,
which is exactly the case now — verified: gross_total null, order_total 2125.5.
