VPN tab: prioritize OPNsense WireGuard, contextual descriptions

When OPNsense WG plugin is detected:
- Show recommendation banner at top explaining why router-level VPN
  is better than running it on the management PC
- OPNsense WG section appears first (recommended path)
- Local WG panels relabeled as "backup / this machine only"
- Local WG description changes to explain the limitation (VLAN 99 only)

When OPNsense is not connected:
- Local WG shown normally as the primary option
- Tip nudge added pointing to DHCP tab to unlock router-level VPN
- OPNsense WG section shown below as a setup prompt

In both cases:
- SSH Tunnel renamed to "Emergency Fallback" with clearer description
- Pre-select servers VLAN when OPNsense WG server becomes available
  (most users want remote access to services, not IoT/cameras)
- Connected Peers / Clients panels prefixed "Local WG —" for clarity
