Add last_status_change_date field for hour-level precision in date filtering

Enhances pending_date and last_sold_date with hour-level precision by introducing the last_status_change_date field. This allows for more accurate filtering of PENDING and SOLD properties when using past_hours parameter. Includes comprehensive tests and version bump to 0.7.1.
