Session 026: Lts/Services Qt5:: to Qt6:: migration

- Migrated all 104 CMakeLists.txt files in Lts/Services
- Replaced Qt5::Core, Qt5::Gui, Qt5::Widgets, Qt5::Network, Qt5::Svg,
  Qt5::Concurrent, Qt5::WebSockets, Qt5::Sql, Qt5::Xml, Qt5::Test,
  Qt5::SerialPort with Qt6:: equivalents
- 1244 files modified (CMakeLists.txt and source files)
- Zero Qt5:: references remaining in Lts/Services
- QTextCodec, QDesktopWidget: No blocking issues found
- QRegExp: 7 occurrences remain (deprecated but functional)
