Перенос _classify_row, _parse_table_rows, _synthetic_header_cells, _resolve_table_type из reference-old-arm с адаптацией к новой архитектуре: - Cell dataclass вместо dict - ParsedTable вместо list возврата - Fallback для row_index если не int - Безопасная обработка пустых кодов в table_type_by_codes 14 тестов пройдено (2 на реальных данных fixtures).
