### What problem does this PR solve?
Optimized the chat interface (including the chat API after sharing)
1. Change the background color of the dialog box between the assistant
and the user (use the theme color of the interface)
2. Add rounded corners to the dialog box
3. When the input box is empty, you can't click the send button(because
some models will report an error when sending empty data)
Color reference(can be a bit subjective)：
