refactor(header): replace emoji icons with Lucide React components and enhance navigation structure

- Introduced `navItems` array with icons and links for streamlined navigation rendering.
- Added `isActive` function to handle active state for improved user feedback.
- Refined desktop and mobile navigation with updated styles and scalable icon usage.
- Removed hardcoded emoji-based navigation for consistency with other components.
