feat(metrics): Add active sessions panel to SecuBox Metrics

- Add get_active_sessions RPCD method to dashboard module
- Display session counts: Tor circuits, HTTPS, Streamlit, Mitmproxy, SSH
- Add ACTIVE SESSIONS panel with yellow/gold theme
- Add RECENT VISITORS panel showing visitor IPs and countries
- Add TOP ENDPOINTS panel showing accessed paths
- Add ACL permissions for get_active_sessions
- Auto-refresh with other metrics every 10 seconds
