Search page:
- Title and breadcrumb now read the station dictionaries and render the
human-friendly route heading (e.g. 'Маршрут: Шереметьево - Пулково')
for route/departure/arrival/flight search URLs, mirroring Angular.
Details page:
- Main H1 becomes 'Информация о рейсе: SU 6805, Москва - Санкт-Петербург'
(carrier + flight number + origin/destination cities), not a bare
flight number.
- Add 'Детали рейса' section header above the accordion to match
Angular's flight-details-wrapper layout.
- Promote the airline block in BoardDetailsHeader: drop the legacy
OperatorLogo copy with broken asset paths and hand off to the shared
<OperatorLogo> under src/ui/flights. Render it with the
'авиакомпания' caption beside the enlarged flight number.
- Replace hardcoded English 'Leg' / 'Total flying time' / 'Aircraft:'
with i18n keys, added to all nine locale files.
Test harness:
- Add vi.mock for useDictionaries in the three suites that render
OnlineBoardSearchPage (the new heading helper calls the hook and
crashed without ApiClientProvider). 1256 tests passing.
