feat(image-zoom): improve zoom interactions and tap detection

- Added `will-change: transform` to CSS for better performance during zoom.
- Enhanced JavaScript to support tap detection for closing the zoom overlay with minimal movement.
- Updated zoom behavior to ensure scaling occurs from the center of the overlay.
- Refined event handling to prevent unintended interactions and improve user experience.
