[srinidhi-2006-bit]

Summary

Fixed the excessive empty vertical spacing between the editor panel and footer by improving the page layout structure and reducing unnecessary spacing.

Closes #509

Changes Made

• Improved root layout structure using flex-based page alignment
• Reduced excessive bottom spacing below the editor panel
• Ensured footer sits naturally beneath editor content
• Preserved responsive behavior across screen sizes
• Verified layout consistency in both dark and light themes

How to Test

1. Run the app locally using bun run dev
2. Open http://localhost:3000
3. Scroll below the editor panel
4. Verify the footer appears without a large empty gap
5. Test on smaller screen widths as well
