Enhance property data handling and intent classification in AI chat

- Updated the `chat_with_session_memory` function to include address data for AI use while ensuring it is not displayed in listings unless requested, improving user privacy and clarity.
- Modified the intent classification logic to recognize requests for addresses, allowing the system to respond appropriately to user inquiries about property locations.
- Adjusted the database schema in `supabase_setup.sql` to add an address field to the properties table and create an index for efficient querying, enhancing data organization and retrieval.
- These changes aim to improve user interaction by providing more comprehensive responses regarding property details while maintaining privacy and clarity in communication.
