When no WiFi credentials are configured or connection fails, the device
automatically starts a soft AP (MimiClaw-XXXX) with a captive portal.
Users can configure WiFi, LLM, Telegram, Feishu, Proxy and Search
settings via a mobile-friendly web page, then the device restarts and
connects with the new credentials.
