Refactor feature shortcodes for improved layout and styling

- Updated the feature shortcode in both `feature.html` files to change the list item class from `items-center` to `items-start` for better alignment.
- Adjusted the SVG icon class to include `flex-shrink-0 mt-1` and set minimum width and height for consistent sizing.
- Enhanced the CSS source map for `custom.css` to improve debugging and maintainability.
