Refactor Tab Styling and Highlight Animation in AreaTabs Component

- Updated tab styling to include a relative positioning for better layout control.
- Introduced a new highlight animation for newly added tabs, replacing the previous background gradient with an opacity fade effect for improved visual feedback.
- Enhanced the tab-highlight class to include a pseudo-element for a more dynamic appearance during animations.
