⚡ Bolt: Optimize images to WebP and fix CLS

[tonymendonca23]

• 💡 What: Converted large PNG/JPG assets to optimized WebP format, resized to near-display dimensions, and added explicit width/height attributes.
• 🎯 Why: To reduce page load size and improve Core Web Vitals (LCP and CLS). The hero image alone was ~800KB.
• 📊 Impact:
  • Total image size reduced by ~82% (~1.1MB -> ~0.2MB).
  • Home image reduced by 6.2x (792KB -> 127KB).
  • CLS score improved by reserving layout space for images.
• 🔬 Measurement: Verified with Playwright script checking natural dimensions and successful loading. File sizes verified via ls.
