Pull Request Overview

This PR adds a dot cursor display option to the noVNC console URL when viewing VMs that don't provide a local cursor or have invisible cursors. This improves user experience by providing visual feedback about cursor position when the VM's cursor is not visible.

• Adds show_dot=true parameter to the noVNC console URL
