refactor: remove CDN tags from feed-map, map, story templates

- feed-map.html.twig: removed MapLibre/toGeoJSON/maplibre-utils CDN tags; added {% do assets.addCss/addJs %} calls directly in partial
- map.html.twig: removed MapLibre/toGeoJSON/maplibre-utils CDN tags; added {% block map_assets %} with Asset Manager registrations
- story.html.twig: removed Scrollama CDN tag (now bundled in main.js as window.scrollama)

All map init and script logic remains unchanged. CDN requests eliminated.
