Subject: [PATCH] feat: add Network Interfaces section and WiFi scan modal to
 Server.vue

Shows detected physical interfaces (ethernet/wifi) with IP, MAC, and
status. WiFi scan button opens a modal with signal strength bars and
password-protected connection flow. Uses network.list-interfaces and
network.scan-wifi RPC endpoints.

 - [x] **BACK-03** — Add WiFi/Ethernet configuration RPC endpoints. Create `core/archipelago/src/network/interfaces.rs` with: `network.list-interfaces` (lists eth0, wlan0, etc. with IP, MAC, status), `network.configure-wifi` (SSID, password, connects via `nmcli`), `network.configure-ethernet` (static IP or DHCP via `nmcli`), `network.scan-wifi` (available networks). Register in RPC router. **Acceptance**: `network.list-interfaces` returns real interface data on dev server.
 
-- [ ] **BACK-04** — Add WiFi/Ethernet UI to Server.vue. Add a "Network Interfaces" section to Server.vue showing detected interfaces with their IPs and statuses. For WiFi, add "Scan & Connect" button that opens a modal listing available networks. For Ethernet, show DHCP/Static toggle. Use `glass-card` container with `bg-white/5` sub-rows. **Acceptance**: Real network interfaces visible on Server page; WiFi scan works on dev server. Deploy and verify.

 - [ ] **BACK-05** — Implement CSRF protection on RPC layer. Address the High-severity finding from `docs/security-audit-2026-03-05.md`. Add CSRF token generation on login (return as cookie + response field), validate on all state-changing RPC calls. In `core/archipelago/src/api/rpc/mod.rs`, add `X-CSRF-Token` header check for non-GET methods. In `neode-ui/src/api/rpc-client.ts`, read the CSRF cookie and send it as header. **Acceptance**: RPC calls without CSRF token return 403; calls with correct token succeed.
