feat: complete CDN elimination + SVG icon build pipeline

CDN cleanup:
- entry.html.twig: remove PhotoSwipe CDN + duplicate JS (main.js handles it)
- dailies.html.twig: remove PhotoSwipe CDN + duplicate JS
- home.html.twig: remove PhotoSwipe CDN + MapLibre CDN + maplibre-utils.js
  script tags; add {% block map_assets %} to register map bundle

SVG build pipeline:
- Add lucide-static devDependency; gen-weather-icons.js reads icon SVGs
  from node_modules and emits templates/partials/weather-icons.html.twig
- package.json build script now runs gen-weather-icons.js before esbuild
- entry-journal.html.twig includes generated partial instead of hardcoded map
- Rebuild: main.js 83.7kb, map.js 860.7kb, all fonts; zero CDN requests remain
