Replace two-step Eurostar fetch (HTML timetable + GraphQL prices) with a
single GraphQL call that returns timing, train numbers, prices, and seats.
Support indirect services (e.g. Amsterdam) by joining multi-leg train numbers
with ' + ' and keeping the earliest arrival per departure time.
Fix half-pound prices by casting displayPrice to float instead of int.
Wrap each train number segment in white-space:nowrap so 'ES 9132 + ER 9363'
never breaks mid-segment.
Format Eurostar prices with two decimal places.
