fix(autoHeightBridge): improve document height measurement and Android handling

Ensure body width/html height are set before measuring, force layout using body offsetHeight as fallback, and use getBoundingClientRect (including html/body rects) for more accurate measurements. Prefer bounding rect heights on Android for better accuracy.
