Live audit of flights.test.aeroflot.ru shows the trail never adds a
third 'leaf' crumb — even on details pages reached with a ?request=
context. React was emitting an extra crumb in three places:
ScheduleSearchPage (route heading), ScheduleDetailsPage (back-to-
search leaf), OnlineBoardDetailsPage (back-to-search leaf). Strip
all three; rewrite the affected unit tests to assert the leaf is
absent; add an e2e parity spec covering all six page types.
