useCitySearch hook loads cities from /api/dictionary/1/cities on first
use, then searches in-memory by name prefix and code -- matching the
Angular CitiesSearchService behavior. Wired into OnlineBoardFilter,
ScheduleStartPage, and FlightsMapFilter AutoComplete components.
Persists search history to localStorage via @/shared/storage with
language-scoped keys (afl_history_{lang}). Supports dedup by URL,
max 10 items, and clear functionality.
Port Angular flight types (ISimpleFlight, IFlightLeg, ITimesSet, etc.)
to minimal React-friendly interfaces. Add formatDuration/formatTime/
formatDate/isDayChange as pure functions. Stub useCityName hook as
passthrough pending customer dictionary API endpoint.
