**Add LAN function and suggestions for optimizing display
**

1. I want the custom model selection to be sorted in alphabetical order by the model's first letter.
2. Network proxy function: can access the Internet by accessing the specified address and port of the LAN device (sock5), bypassing some LLM restrictions on the user's IP address.
3. Web browser function: Other devices in the local area network can access the Android chatair application (WEB mode) through the browser, based on an address similar to https://192.168, so as to realize the multi-device use of the APP without developing new applications.
