Schedule row click opens flight details (TIRREDESIGN-4)

FlightList on direction=schedule now wires a row-level onClick so the
entire row navigates to the details page instead of expanding inline.
Matches Angular's schedule-search-result behaviour where each flight
row is a link to the details card.
