feat: streamline navbar UI and cleanup base layout

Updated the padding in the navbar links for a more compact appearance, enhancing user interface clarity and consistency. Added margin auto to `.navbar-btn` for better visual symmetry, contributing to a more polished overall layout. Removed unnecessary line breaks (`<br>`) in the base template for a cleaner, more streamlined code and user experience. These adjustments align with our continuous efforts to improve UI aesthetics and usability.
