Subject: [PATCH] feat: configure Vite proxy and Nginx for WebSocket traffic
 (#8)

- Add /ws proxy entry in vite.config.ts with ws: true (dev)
- Add location /ws block in nginx.conf with upgrade headers and
  proxy_read_timeout 86400s (production)
- Fix pre-existing wrong port 8080 -> 8081 for /api proxy in both files
