This pull request includes updates to the OsocWidget to improve the handling of SVG images and enhance the UI. The most important changes involve adding a new dependency, updating the widget to use a new SVG handling package, and making UI adjustments.

Dependency Updates:

• pubspec.yaml: Added jovial_svg dependency to the project.

Widget Updates:

• lib/widgets/osoc_widget.dart: Imported the jovial_svg package.
• lib/widgets/osoc_widget.dart: Updated the OsocWidget to use ScalableImageWidget from jovial_svg for displaying SVG images, replacing the previous SvgPicture.network implementation. This includes wrapping the image in a ClipRRect with rounded corners and setting fixed dimensions.
