Add torrent copy operation monitoring

Add real-time monitoring of torrent copy operations when completed
downloads are copied from SSD to HDD storage.

Changes:
- Add marker file tracking during rsync operations
- Monitor active copy operations via /tmp/torrent-copy-active
- Display copy status as sub-service under openvpn-vpn-download
- Show currently copying torrent name in dashboard

The copy status appears as an informational sub-service while rsync
is actively copying completed torrents to permanent storage, providing
visibility into potentially long-running file transfer operations.
