perf: optimize bundle size and add build optimizations

- Move HTML stripping to server-side to remove cheerio from client bundle (247KB reduction)
- Add terser minification with console/debugger removal
- Enable manual code chunking for chart.js and auth libraries
- Convert TTF fonts to WOFF2 format (~900KB savings)
- Enable brotli/gzip precompression in adapter
- Update CSS to prefer WOFF2 with TTF fallback
