fix: Fix build with Qt 6.9

Qt 6.9 removed QAbstractFileEngine::beginEntryList/endEntryList.
The ddcifileengine.cpp still provided an implementation of
beginEntryList() which is no longer part of the base class,
causing build failures with Qt 6.9.

Log: remove QAbstractFileEngine::beginEntryList for Qt 6.9+
