Make app fully responsive for mobile devices

- Configure Monaco Editor with mobile-optimized settings (larger font, better touch support)
- Refactor layout with proper responsive breakpoints (mobile < 768px, tablet < 1024px)
- Stack editor and output vertically on mobile for better usability
- Optimize all interactive elements with 44px minimum touch targets
- Use responsive font sizing (clamp) in header for better mobile display
- Fix toolbar overflow with flex-wrap and responsive spacing
- Add font-size: 16px to form inputs to prevent iOS zoom
- Simplify FileUpload UI on mobile (hide drag text, stack buttons)
- Make bottom bar flexible for mobile screens
- Clean up and consolidate CSS media queries across all components
