Enhance intent classification to include request_details

- Updated the classification logic in `extract_and_update_intent` and `extract_and_search_properties` to recognize "request_details" as a valid classification, allowing the system to handle specific property inquiries more effectively.
- Expanded the documentation to clarify the intent classification options and provided examples for better user understanding.
- These changes aim to improve the AI chat's responsiveness to user requests for detailed property information, enhancing overall user experience.
