Waypoints snapped to OSM POIs in the Planner now carry their metadata all
the way through to the Journal:
- Extend Waypoint type with osmId and poiTags fields
- Extract osmId/poiTags from Yjs Y.Map in ExportButton and SaveToJournalButton
- Encode POI metadata as <trails:poi> extensions in GPX <wpt> elements
- Parse <trails:poi> extensions back in the GPX parser
- Display phone, website, opening hours, address on Journal route detail
- E2E test for the full roundtrip; seed endpoint now defaults to public visibility
