feat: Add Portal, Hub, Admin sections to portal navigation

Update portal.js sections to include:
- Portal (home page)
- Hub (SecuBox dashboard)
- Admin (Admin Control Panel)
- Security, Network, Monitoring, System (existing)

Update index.js to render Portal/Hub/Admin as links to separate
pages while keeping Security/Network/Monitoring/System as tabs.
