feat: implement scene deletion functionality

Added a new `SceneDeleteView` to `views.py`, enabling users to delete scenes directly from the UI. The corresponding URL pattern for scene deletion has been defined in `urls.py`. In addition, the category template (`category.html`) has been updated to include delete action icons alongside existing edit/view actions for each scene. This update enhances user control by allowing for the efficient management and removal of scenes from a project's category listing.

This change addresses user feedback requesting more intuitive content management capabilities within the application. Particularly, it simplifies the workflow for users managing large numbers of scenes, improving the overall user experience by streamlining content administration tasks.
