This commit implements the core routing functionality for the trip planner MVP:
1. API handlers for city autocomplete, station listing, route search, and route GeoJSON
2. Router integration with Yandex Schedules API for building routing graphs
3. Pareto-optimal route search with max 1 transfer and MCT filtering
4. Cron job for station status detection and closure monitoring
5. Circuit breaker and rate limiter integration in Yandex client
6. Redis cache-aside layer for city directories and station lists
