Проблема: Backend proxy не передавал filename и upload_timestamp к n8n
Это ломало обработку файлов в workflow
Изменения:
- Добавлены параметры filename и upload_timestamp в proxy_file_upload()
- Теперь передаём все поля которые отправляет frontend
Было в n8n body: {claim_id, voucher, session_id, file_type}
Стало: {claim_id, voucher, session_id, file_type, filename, upload_timestamp}
