Add trip linking and names to Schengen compliance report

- Add trip_date and trip_name fields to SchengenStay dataclass
- Implement extract_schengen_stays_with_trip_info() to associate stays with trips
- Update schengen_report.html to show trip names with clickable links
- Add Trip column to stays table and trip name column to compliance history
- Links navigate to individual trip pages using existing URL structure

Closes #197
