feat: modify the background color of chat messages #1215

### Type of change

- [x] New Feature (non-breaking change which adds functionality)

### 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)：

### What problem does this PR solve?

The restricted_loads function at
[api/utils/init.py#L215](https://github.com/infiniflow/ragflow/blob/main/api/utils/__init__.py#L215)
is still vulnerable leading via code execution. The main reson is that
numpy module has a numpy.f2py.diagnose.run_command function directly
execute commands, but the restricted_loads function allows users import
functions in module numpy.
