fix: Improve Lighthouse CI server startup reliability

🔧 Lighthouse CI improvements:
1. ✅ Extended server ready timeout from 30s to 120s (2 minutes)
2. ✅ Enhanced ready pattern to match multiple Next.js startup messages
3. ✅ Added additional Chrome flags for CI environment stability
4. ✅ Reduced number of runs from 3 to 1 for faster CI execution
5. ✅ Better error handling for server startup issues

🎯 Root cause fixes:
- Server timeout issues in CI environment
- Chrome interstitial errors due to server not being ready
- Improved pattern matching for Next.js startup messages

This should resolve the 'Chrome prevented page load with an interstitial' errors.
