- Always show three-tab layout (RouterOS, SNMP, VPN) instead of conditional two-tab
- RouterOS tab: credential profile toggle (profile mode vs manual credentials)
- SNMP tab: version selector (v2c/v3), credential profile, device profile, port
- Both tabs have "Add Multiple" toggle to switch to BulkAddForm
- VPN tab renders existing VpnOnboardingWizard unchanged
- All form state resets on dialog close
