feat: improve image dimension detection in property dialog

- Add QImageReader as fallback method when properties don't contain width/height
- Optimize condition checks in imageExtenInfo function
- Add QImageReader header inclusion
- Add comments to explain the fallback logic

This change enhances the reliability of image dimension detection,
especially for image formats that don't provide dimension information
in their properties.
