Problem: cropper always called out.toBlob(..., 'image/jpeg') regardless
of the original file type, silently converting PNGs to JPGs.
Fix:
- openCropper() now stores file.type and file.name on the cropper object
- applyCrop() uses the stored mime type for toBlob() and the filename
- Quality param only passed for lossy formats (jpeg/webp), not for PNG/GIF
- uploadImage() accept list expanded: svg, ico allowed
- Server-side: .svg and .ico added to allowed extensions
Result: PNG stays PNG, WebP stays WebP, ICO stays ICO.
