feat: Trip Detail as chronological timeline (matches web dashboard)

Replaced type-grouped sections with a unified timeline:
- All items (flights, lodging, places) sorted by date + time
- Grouped by day with "Tuesday, Jan 20" headers
- Vertical timeline line connecting items within each day
- Color-coded icons: blue (flights), warm (lodging), red (places)
- Time shown in 12h format (8:50 AM)
- Category badges for places
- Subtitle with route/location details

Same layout order as the web dashboard — not grouped by type.
