Optimize UI for mobile devices with minimal design

- Add responsive mobile navigation with icon buttons
- Implement rounded corners throughout UI (1-2rem radius)
- Remove all animations for instant, clean transitions
- Create PWA manifest and app icons for mobile experience
- Reorganize header: removed hamburger menu, simplified layout
- Change "Create Account" to "Register" for consistency
- Ensure single-row header layout across all screen sizes
- Mobile: Show icon buttons (👤 for Login, ➕ for Register)
- Desktop: Show text buttons for Login and Register
- Improve touch targets (min 48px) and spacing on mobile
- Add mobile-first responsive breakpoints
- Black & white minimal design maintained throughout
