Refactor travel segments and simplify trip options

Travel segment architecture:
- Remove departureTime/arrivalTime from TravelSegment (location-based, not date-based)
- Fix travel sections appearing after destination instead of between cities
- Fix missing travel segments when revisiting same city (consecutive grouping)
- Remove unwanted rest day at end of trip

Planning engine fixes:
- All three planners now group only consecutive games at same stadium
- Visiting A → B → A creates 3 stops with proper travel between

UI simplification:
- Remove redundant sort options (mostDriving/leastDriving, mostCities/leastCities)
- Remove unused "Find Other Sports Along Route" toggle (was dead code)
