75c245cde7 implement client-side pending_date filtering for PENDING properties
- Fix PENDING properties to filter by pending_date instead of list_date
- Add client-side filtering for PENDING as server-side pending_date filter is broken
- Include contingent properties without pending_date for comprehensive results
- Enhance documentation to clarify past_days behavior per listing type
- Add property_history field to GraphQL queries for future enhancements
- Add comprehensive test for pending date filtering functionality
- Optimize filtering logic with helper methods for better maintainability
