ScheduleStartPage previously stored the raw IATA code from the prefill
in departureAirport / arrivalAirport state, so PrimeReact's AutoComplete
would render 'MOW' (or 'SVO' before the prior commit) literally in the
input. Now, once dictionaries resolve, the effect replaces each string
slot with a { code, name } object so the autocomplete shows 'Москва'.
Mirrors Angular CityAutocomplete.writeValue → getCityOrAirport, which
upgrades the bound string to a CityModel for display while keeping the
code as the outbound form value.
