CustomZoomableImage class
A widget that displays an image and allows pinch-to-zoom functionality.
CustomZoomableImage wraps an Image widget with a GestureDetector
to capture scale gestures, enabling the user to zoom in and out. The zoom
level is restricted to a minimum of the original size (1.0) and a maximum
of 3.0 to prevent excessive zooming.
