Improve navbar responsiveness across all devices

Is your feature request related to a problem? Please describe.

The current navbar does not provide an optimal experience across all screen sizes. On smaller devices, navigation items may appear crowded, spacing can become inconsistent, and the overall usability of the navigation menu is reduced. Additionally, touch interactions and accessibility features could be improved to provide a smoother user experience on mobile and tablet devices.

Describe the solution you'd like

Implement a fully responsive navbar that adapts seamlessly to different screen sizes. The improved navbar should include:

• A mobile-friendly navigation menu with a hamburger toggle.
• Consistent spacing and alignment across devices.
• Improved touch targets for mobile users.
• Smooth animations and transitions for menu interactions.
• Enhanced keyboard navigation and accessibility support.
• Better support for light and dark themes.
• Prevention of overflow and layout issues on smaller screens.

Describe alternatives you've considered

• Maintaining the existing navbar layout and making only minor CSS adjustments.
• Using a simplified navigation structure for mobile devices.
• Introducing a sidebar-based navigation experience instead of a dropdown mobile menu.

While these alternatives may address some issues, a fully responsive navbar provides the most consistent and user-friendly experience across all devices.

Additional context

This enhancement aims to improve usability, accessibility, and visual consistency throughout the application. The changes should be tested across mobile, tablet, and desktop viewports to ensure reliable behavior and responsiveness.
