Merge branch 'feature/web-vitals-optimization' into dev

- Font optimization: Replace @font-face with next/font/google (DM Sans, Inter) for faster font loading and no render-blocking
- Image optimization: Add Unsplash to remotePatterns, configure AVIF/WebP formats, add device/image sizes
- Convert native <img> tags to next/image with proper sizing and priority for LCP images
- Add optimizePackageImports for lucide-react and framer-motion to reduce bundle size
- Fix CLS: Urgency message uses fixed min-height instead of animated height
- Fix CLS: ProductCard quick-add button uses opacity instead of translate for hover
- Convert HeroVideo scroll indicator to CSS animation
- Script loading: Rybbit uses lazyOnload strategy for better INP
