Stream GWR walk-on fares client-side instead of blocking page render

Browse source 
Walk-on fares are now always fetched in the browser via WALKON_API_URLS
rather than synchronously on the server. This means the page renders
immediately with timetable and Eurostar prices, and NR fares fill in
shortly after without delaying the initial load.
