✨(frontend) enhance dropdown menu and quick search components

- Added a horizontal separator to the dropdown menu for better visual
distinction between options.
- Updated padding in the quick search input for improved layout
consistency.
- Adjusted margin in the quick search group for better spacing.
- Increased vertical padding in quick search item content for enhanced
readability.
- Modified the horizontal separator to accept custom padding for more
flexible styling.
- Improved left panel styling to manage overflow behavior effectively.
- Removed unused skeleton loading styles from globals.css to clean up
the codebase.
