Navbar design

[Nishankulal03]

In this update, I made several design changes to enhance the user experience. Firstly, I adjusted the navbar position to be fixed, ensuring it remains at the top of the viewport while scrolling. Additionally, I updated the theme toggle icon to be initially hidden, improving the overall layout. Some navbar items are now also hidden initially, which helps to focus the user's attention on the primary options. Lastly, I ensured that the logo is properly displayed within the navbar for better branding.
