[w2naf]

Description

1. Download the current version of Leaflet.js and Leaflet CSS
2. Place files in an appropriate vendor directory (e.g., static/vendor/leaflet/)
3. Include Leaflet marker icon images locally
4. Update HTML templates to reference local files instead of CDN URLs
5. Verify the map loads correctly without any network requests to external servers
