Added `image-rendering` properties and opacity transitions to `.pdf-canvas` for smoother visual effects during rendering. Introduced a `.pdf-canvas.rendering` class to indicate rendering state. Enhanced `renderPage` method to support HiDPI displays by scaling the viewport based on device pixel ratio (up to 2) and setting both internal resolution and CSS display size for better rendering quality. Enabled high-quality rendering with `imageSmoothingEnabled` and `imageSmoothingQuality`. Updated scroll container reference to `.pdf-canvas-wrapper` for proper alignment. Added logic to manage the `rendering` class during and after rendering, including error handling to ensure UI consistency. These changes improve both functionality and aesthetics of the PDF viewer.
