When NEXT_PUBLIC_WS_URL is not set, the WebSocket URL defaulted to ws://localhost:8080/ws. This broke real-time features (chat streaming, live updates, notifications) for self-hosted deployments accessed over LAN — the browser tried connecting to localhost on the client machine instead of the Docker host. Now the web app derives the WebSocket URL from window.location, routing through the existing Next.js /ws rewrite. This works for localhost, LAN, and custom domain setups without any extra configuration. Also adds NEXT_PUBLIC_WS_URL as a Docker build arg for explicit override, and documents LAN access configuration in SELF_HOSTING_ADVANCED.md. Closes #896
