Fix docker volume prune command to properly remove volumes

The previous implementation used 'docker volume prune' which only removes
unused/dangling volumes. Volumes created by Docker Compose remain referenced
even after containers are stopped/removed, so prune wouldn't delete them.

Changed to explicitly list volumes by label filter and remove them using
xargs. This ensures all project volumes are deleted when running 'make prune'.

Changes:
- Replace 'docker volume prune' with 'docker volume ls | xargs docker volume rm'
- Add error suppression for cross-platform compatibility (BSD/GNU xargs)
- Add confirmation message showing which project's volumes were removed
