- Унифицирован формат номеров документов: IN-XXXXXX (6 цифр), как WO-XXXXXX и MOVE-XXXXXX - Убрано дублирование функции _extract_number_from_document_number - Оптимизирована инициализация счетчика incoming: быстрая проверка перед полной инициализацией - Удален неиспользуемый файл utils.py (функциональность перенесена в document_generator.py) - Все функции генерации номеров используют единый подход через DocumentCounter.get_next_value()
