Redesign trip option cards and fix various UI/planning issues

TripOptionCard improvements:
- Replace horizontal route with vertical layout (start → end with arrow)
- Remove rank badges (1, 2, 3, etc.)
- Split stats into two rows: cities/miles and sports with game counts
- Clear selection when navigating back from detail view

Settings cleanup:
- Remove unused settings (preferred game time, playoff games, notifications)
- Convert remaining settings to sliders

Planning fixes:
- Fix multi-day driving calculation in canTransition
- Remove over-restrictive trip rejection in TravelEstimator
- Clear games cache when sport selection changes

UI polish:
- RoutePreviewStrip shows all cities (abbreviated)
