Fix production build with esbuild minification

- Switch from Terser to esbuild minifier (Vite's default)
- Set target to es2015 for better browser compatibility
- Remove manual chunking that was causing load order issues
- Result: 3MB bundle (down from 6.5MB) with proper minification

This should resolve the production build errors caused by improper
chunk loading order and duplicate module bundling.
