⚡ Bolt: Optimize images and prevent CLS

[tonymendonca23]

• 💡 What: Converted PNG/JPG assets to WebP, resized them to display dimensions, and added explicit width/height attributes to HTML.
• 🎯 Why: To improve load performance (LCP) and prevent Cumulative Layout Shift (CLS).
• 📊 Impact: Reduced hero image size by ~93% (792KB -> 59KB). Eliminates layout shifts on image load.
• 🔬 Measurement: Visual verification via Playwright screenshot and programmatic check of HTML attributes.
