Refactor intent extraction and flow control for improved user interaction

- Updated the `extract_and_update_intent` function to set the response directly in the state when prompting users for location during property searches, enhancing clarity and flow.
- Modified the `should_continue` function to improve readability and debugging by explicitly checking for the presence of a response, ensuring better control over the conversation flow.
- These changes aim to streamline user interactions by ensuring that location preferences are addressed effectively and that the decision-making process in the chat flow is more transparent.
