Initial release: collaborative trip planner

Multi-user trip planning web app in a single Docker container. Mullvad-style token accounts, trip sharing via join codes, day-by-day calendar with typed entries (activity, hotel, travel, flight, rental car, immigration, note), multi-leg flight segments with bundled IATA airport dataset, Leaflet/OSM map with per-leg great-circle km (air vs ground), rough km-driven vs rental included-km comparison, cost splitting with settle-up suggestions, flip-clock departure countdown. Node 20 + Express + SQLite (WAL, additive migrations), vanilla JS SPA, 44 API tests.
