Improve search result layout and spacing

Adjusted the search result layout and added more consistent spacing in the search results page. This makes the display cleaner and easier to read for users. 

Changes:
- Changed list styling for flex display and added a `-mr-14` class to control the layout.
- Updated spacing between elements using both `flex-col gap-6` and `mr-14` to provide more consistent separation between items.
