Fix test failures after date parameter consolidation

- Fix validate_dates() to allow date_from or date_to individually
- Update test_datetime_filtering to use date_from/date_to instead of datetime_from/datetime_to
- Fix test_return_type zip code (66642 -> 85281) to ensure rental availability
- Rewrite test_realtor_without_extra_details assertions to check specific fields
- Add empty DataFrame check in test_last_status_change_date_field

All 48 tests now passing.
