Subject: [PATCH] Session 025: Fix QTextCodec migration issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Z/src/qsql_informix/qsql_informix.cpp: Fixed QTextCodec include path
  (QtCore → QtGui) as QTextCodec moved to QtGui module in Qt6
- Z/src/qsql_informix/CMakeLists.txt: Added Qt6::Gui dependency required
  for QTextCodec
- Lts/Tools/TextEditorTest/textedit.cpp: Fixed Qt::codecForHtml →
  QTextCodec::codecForHtml (static method on QTextCodec class in Qt6)

These are minimal fixes required for Qt6 compatibility. QTextCodec is now
part of QtGui module and codecForHtml is a static method on QTextCodec
class rather than Qt namespace function.
