Summary by Sourcery

Redesign the Collapse component's HeaderTemplate to render inside the header button and prioritize it over icons and text, and update sample usage accordingly

Enhancements:

• Render HeaderTemplate inside the collapse header button and adjust display priority over icons and text
• Streamline sample usage by removing unnecessary wrapper divs around HeaderTemplate

Reviewer's Guide

This PR redesigns the Collapse component’s header template handling by consolidating template, icon, and text rendering into the header button for clearer conditional logic, and streamlines sample usage by removing unnecessary wrappers.
