Per TZ §4.1.4 Table 7 rows 6–8, the details page now builds a 3-item
breadcrumb trail [Home, Онлайн-Табло, <leaf>] where <leaf> is mode-aware:
- flight: "Номер рейса: SU-1234" (hyphen per TZ)
- departure: "Вылет: {station}"
- arrival: "Прилет: {station}"
- route: "Маршрут: {dep}-{arr}"
The leaf crumb is a clickable link back to the source search page with
time-range preserved in the URL. Share-link entries (no ?request=) get
only [Home, Онлайн-Табло] with no leaf.
Breadcrumbs component updated to allow last-item links (was suppressed),
since TZ explicitly requires the leaf to be navigatable.
CONFLICT (deferred to Task 16): TZ row 6 says departure/arrival leaf
should show both dep+arr cities; parentRequest only carries one station,
so only that station is shown. Departure/arrival search returns flights
to many arrival cities — "both cities" makes no sense at search-mode level.
