Fix coast-to-coast trips and improve itinerary display

- Fix same-day different-city validation in C2C routes (no more impossible
  games like Detroit 7:30pm AND Milwaukee 8pm on the same day)
- Cap C2C trips at 14 days max with 3 middle stops, prefer shortest routes
- Add sport icon and name to game rows in trip itinerary
- Add horizontal scroll to route dots in suggested trip cards
- Allow swipe-to-dismiss on home sheet (trip planner still blocks)
- Generate travel segments for suggested trips
- Increase DAG route lookahead to 5 days for multi-day drives
