[FIX]: Implement Dark Mode Consistency for Navigation Bar and Buttons

In the project's dark mode, inconsistency exists where the navigation bar, icons, and buttons retain their light mode appearance. This issue aims to ensure uniformity across both light and dark modes by adjusting the styling of the navigation bar, icons, and buttons to align with the dark mode theme. By addressing this issue, we aim to provide users with a seamless visual experience in both modes, enhancing accessibility and aesthetics.

Kindly assign this task to me, and I'll begin working on harmonizing the design elements accordingly. Thank you for the opportunity to contribute!
