Initial commit: Flights iOS app

Flight search app built on FlightConnections.com API data.
Features: airport search with autocomplete, browse by country/state/map,
flight schedules by route and date, multi-airline support with per-airline
schedule loading. Includes 4,561-airport GPS database for map browsing.
Adaptive light/dark mode UI inspired by Flighty.
