fix(epf-dump): постусловие выходного каталога + маскировка учётных данных

Пропущенный при разборе #49-52 навык того же класса: epf-dump разбирает EPF/ERF
через платформу в каталог XML. Успех определялся только по коду возврата (ложный
успех при пустом выходе), а строка Running светила /P<пароль> (1cv8) и --password=
(ibcmd). Добавлены postcondition непустого OutputDir и маскировка, обе ветки,
оба порта. Покрывает и erf-dump (общий скрипт).
