perf(websocket): switch WiFi to performance mode before connecting (#1985)

* perf(websocket): switch WiFi to performance mode before connecting

Optimize WebSocket connection speed by switching WiFi to performance
mode before establishing the connection, instead of after.

This reduces network latency significantly:
- TCP connection: 1093ms → 88ms (92% faster)
- WebSocket handshake: 1035ms → 80ms (92% faster)
- Total network layer: 2128ms → 173ms (92% faster)

The issue was caused by WiFi power save mode (MAX_MODEM) which adds
significant latency to packet transmission.

* Adjust formatting

+1. 确认 Otto 已连上 WiFi，获取 IP 地址（可通过小程序或串口日志查看）
+2. 打开任意 WebSocket 调试工具（如 [websocket.org/echo](https://websocket.org/echo) 或浏览器控制台）
