Add SSH connection information to web UI

This commit implements:
1. Added SSH information display to the web UI info button
2. Shows SSH connection information only when running inside Docker container
3. Constructs the full SSH hostname as "sketch-[session_id]"
4. Added copy-to-clipboard buttons for SSH commands
5. Styles the VSCode URL as a proper clickable link
6. Shows a warning message when SSH is not available
7. Modified container naming to use only SessionID instead of imgName+SessionID
