Функция uploading_files_to_server, закачивает файл на сервер. После нажатия на файл в дереве каталогов Файл начинает отправляться на сервер.

progress() - не вижу где определенна.
туда подставь сигнал, который свяжи с прогресс баром.
Выгрузку файлов нужно обернуть в QRunnable или QThread.
Если выделить код, который не работает с интерфейсом в отдельный класс - то не требуется каждую функцию отдельно отправлять в тред. В тред отправляется весь класс. Также разделение интерфейса и логики делает код проще для модернизации.
Вот отрефакторил минимальный пример на сигналах - слотах:
