Improve table font size and optimize website loading performance

- Increase table font sizes for better readability:
  * Body cells: 13px → 16px
  * Header cells: 15px → 18px
  * Footer cells: 14px → 16px
  * Total cells: 15px → 17px

- Add performance optimizations:
  * Add preconnect hints for external CDNs and APIs
  * Add defer attribute to non-critical JavaScript files
  * Add font-display: swap to improve perceived loading speed
