Show POI details (phone, website, opening hours) on Journal route detail page

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
