Implement Service Registry LuCI app for unified service management:
- RPCD backend aggregating services from HAProxy, Tor, netstat, LXC
- One-click publish to clearnet (HAProxy+ACME) and/or Tor hidden service
- Static landing page generator with QR codes for all URLs
- LuCI dashboard with service grid, quick publish form
- CLI tool (secubox-registry) for command-line management
- Share buttons for X, Telegram, WhatsApp
RPCD methods: list_services, publish_service, unpublish_service,
generate_landing_page, get_qr_data, list_categories
