Edward Betts 06afd57957 Link to Eurostar search page with pricing; add Bristol departures RTT link 
Replace the Eurostar timetable link with the search URL
(eurostar.com/search/uk-en?adult=1&origin=…&destination=…&outbound=…)
so the footer links directly to the page that shows prices for the
specific date and destination.

Add a Bristol Temple Meads → Paddington departures link on RTT alongside
the existing Paddington arrivals link.

Also update "morning service unavailable" badge and tests to reflect the
removal of the morning-only cutoff filter from find_unreachable_morning_eurostars.
