feat: add trip/trips/stories templates, update nav and map/stats to use trip-relative paths

- Rename tracker.html.twig to dailies.html.twig; update dailies.md template key
- Fix map.html.twig and stats.html.twig: find dailies via page.parent().route
- Update base.html.twig nav to use config.site.active_trip for all hrefs
- Fix dailies.html.twig mini-map link to use page.parent().url/map
- Create trip.html.twig, trips.html.twig, stories.html.twig
