- WireGuardManager: get_external_ip() (cached 1h), check_port_open(),
get_server_config() returning public_key + detected endpoint
- API: /api/wireguard/server-config returns real external IP;
/api/wireguard/refresh-ip forces re-detection;
/api/wireguard/peers/config now looks up peer IP + private key from
registry and uses real server endpoint automatically
- Fix doubled port in Endpoint (178.x:51820:51820 → 178.x:51820)
- Fix Address=/32 when peer_ip already has mask
- WebUI nginx: proxy /api/ and /health to cell-api (fixes localhost:3000
hardcode — UI now works from any machine)
- api.js: baseURL='' so all calls go through nginx proxy
- WireGuard page: show Server Endpoint card with external IP, endpoint,
public key, and Refresh IP button
