Add region-based filtering and route length diversity

- Add RegionMapSelector UI for geographic trip filtering (East/Central/West)
- Add RouteFilters module for allowRepeatCities preference
- Improve GameDAGRouter to preserve route length diversity
  - Routes now grouped by city count before scoring
  - Ensures 2-city trips appear alongside longer trips
  - Increased beam width and max options for better coverage
- Add TripOptionsView filters (max cities slider, pace filter)
- Remove TravelStyle section from trip creation (replaced by region selector)
- Clean up debug logging from DataProvider and ScenarioAPlanner
