Show Eurostar seat availability and no-prices notice

fetch_prices now returns {'price': ..., 'seats': ...} per departure.
Seat count (labelled "N at this price") is shown below the fare — it
reflects price-band depth rather than total remaining seats. A yellow
notice is shown when the API returns journeys but all prices are null
(tickets not yet on sale).
