refactor: TripDetailView loads games on demand, improve poll UI

- Refactor TripDetailView to fetch games from AppDataProvider when not
  provided, adding loading state indicator for better UX
- Update all callers (25+ HomeContent variants, TripOptionsView, HomeView)
  to use simpler TripDetailView(trip:) initializer
- Fix PollDetailView sheet issue by using sheet(item:) instead of
  sheet(isPresented:) to prevent blank screen on first tap
- Improve PollDetailView UI with Theme styling, icons, and better
  visual hierarchy for share code, voting status, and results sections
