fix: resolve 4 UI/planning bugs from issue tracker

- Lock all maps to North America (no pan/zoom) in ProgressMapView and TripDetailView
- Sort saved trips by most cities (stops count)
- Filter cross-country trips to top 2 by stops on home screen
- Use LocationSearchSheet for Follow Team home location (consistent with must-stop)
- Initialize DateRangePicker to show selected dates on appear
