fix(pdf): include all trip days in PDF export

Fixed PDF export missing the last day when games occur on departure date.

Root cause: Trip.itineraryDays() calculated lastActivityDate as departure - 1,
assuming departure is always after the last activity. When games happen ON the
departure date, that day was skipped.

Fix: Check if the last stop has games. If so, include the departure date in
the itinerary loop.

Also includes:
- buildCompleteItineraryItems() to merge games, travel, and custom items
- Magazine-style PDF layout with sport-specific accent colors
- Proper iteration over all trip days in PDF generator
