Adds a visual loading spinner to the `visual-image-tool`. The spinner is displayed when the tool is instantiated and the image is loading. It is hidden once the image is fully loaded and the tool's UI elements are ready. This improves your experience by providing visual feedback during the initial loading phase, preventing the perception of unresponsiveness. Changes include: - Added `this.spinnerElement` and `this.initialLoadComplete` fields. - Created and styled a spinner DIV element in `_prepareContainer()`. - Added CSS keyframes for the spinner animation. - Implemented logic in `_updateScaling()` to hide the spinner upon initial image load. - Ensured the spinner element is removed in the `destroy()` method.
