Session 022: Migrate Lts/Tools (72 submodules) to Qt6

- Copied complete Lts/Tools directory from qt5-before to qt6-after
- Updated 32 CMakeLists.txt files (Qt5:: → Qt6::)
- Tools subdirectory already included in parent Lts/CMakeLists.txt
- All 72 tool submodules now present in qt6-migrated-legatus
- Includes: Adler, ArAssets, ConfigX, DBAdministration, DBUpdate,
  DdsView, InfrastructureManagement, and 67 more tools
- C++17 standard (RTI 7.7.0 compatibility maintained)
- Tests deferred until final validation phase

Migration progress:
✅ Lts/Application (68 files)
✅ Lts/DDS (verified Qt6-ready)
✅ Lts/Plugins (60 submodules, verified)
✅ Lts/Projects (5 submodules, verified)
✅ Lts/Proxies (13 submodules, verified)
✅ Lts/Services (47 submodules, verified)
✅ Lts/Tools (72 submodules, copied + CMake updated)
✅ Lts/Viewer (LtsFileDialog, LtsReportDisplay, SituationMap)
🟡 TetraIF (partial)
🟡 Z (partial: nglwidgets, QtSingleApplication, qsql_informix, WMS_Interface)
