Bundle all vendor JavaScript files locally instead of loading from CDNs
This change eliminates all external CDN dependencies by bundling JavaScript
libraries locally using esbuild. All vendor files are now served from the
application's own assets, improving reliability and privacy.

Changes:
- Created assets/js/vendor.js to bundle all external libraries
- Added vendor bundle configuration to esbuild in config files
- Updated all templates to use local vendor.js instead of CDN scripts
- Created download-vendor-files.sh script to fetch vendor libraries
- Added vendor files to .gitignore (they're downloaded during setup)
- Updated CSS imports to include vendor stylesheets
- Added vendor build step to assets.deploy mix task

Bundled libraries:
- Leaflet 1.9.4 (mapping library)
- Leaflet.heat 0.2.0 (heatmap plugin)
- Leaflet.markercluster 1.5.3 (marker clustering)
- OverlappingMarkerSpiderfier 0.2.6 (overlapping marker handling)
- Chart.js 4.5.0 (charting library)
- chartjs-adapter-date-fns 3.0.0 (date adapter for Chart.js)

All functionality tested and working correctly with local bundles.
