test(query_list): fix type hints and error handling
why: Tests had incorrect type hints and error handling assertions what: - Updated type hints to use Mapping instead of dict for better type variance - Fixed variable name reuse in test_filter_error_handling - Added proper type casting for testing invalid inputs - Improved test assertions to match actual behavior
