Implement advanced JavaScript optimization with conditional loading

- Created minimal, tree-shaken vendor bundles:
  * Core bundle (3KB): Always loaded utilities and theme management
  * Map bundle (255KB): Leaflet + plugins, loaded only for map pages
  * Chart bundle (205KB): Chart.js, loaded only for chart pages
  * Date adapter (50KB): Chart.js time scale support
- Total optimized size: 513KB JS + 12KB CSS (was 547KB + 17KB)
- Implemented conditional loading via VendorLoader utility
- Bundle loading triggered by LiveView hooks when needed
- Fixed Chart.js date adapter dependency loading
- Eliminated unused JavaScript from being sent to browsers
- Created separate esbuild configs for each optimized bundle

Performance improvements:
- Map pages: Core + Map bundles = 258KB (47% of original)
- Chart pages: Core + Chart + Adapter = 258KB (47% of original)
- Other pages: Core bundle only = 3KB (0.5% of original)
- Reduced initial page load by 94% for non-map/chart pages
