fix(locations): add referrerPolicy to OSM tile layers

Add referrerPolicy: 'origin' to the Leaflet tile layer in
geolocation_list.html and geolocation_detail.html to match the

Without this, those templates send the full page URL as Referer,
which can trigger OSM rate limiting (osm.wiki/blocked error).

Also marks the task as DONE in PROJECT.org.
