### What problem does this PR solve?  
- The API documentation lacks detailed error code explanations. Added
error code tables to `python_api_reference.md` and
`http_api_reference.md` to clarify possible error codes and their
meanings.
- Error handling in the codebase is inconsistent. Standardized error
handling logic in `sdk/python/ragflow_sdk/modules/chunk.py`.
- Improved API comments by adding standardized docstrings to enhance
code readability and maintainability.

add non-stream mode support to session.ask function

### What problem does this PR solve?

same as title, I do not know why the stream=False is not work on the
server side also, when stream=False, the response in the
session._ask_chat is a fully connnected SSE string.

This is a quick fix on the sdk side to make the response format align
with API docs
