implemented RMV public transit module including trip search, station departures, and nearby stop lookup, added "Marianum Connect" API integration with bearer token authentication and auto-refresh logic, integrated geolocator for location-based station search, added persistent storage for favorite stations and recent trip queries, and implemented comprehensive UI for journey details, trip results, and disruption alerts
