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)

+QLedMatrix Widget
+-----------------
+
+      The QLedMatrix widget simulates a LED matrix (dot matrix) display.
+
+      A LED matrix display is a 2-dimensional array of dots used to generate
+      characters, symbols and images. It is often seen on machines, clocks and
+      display boards.
+
+      This generic implementation can configured for any size of rows (greater
+      than 0) and columns. The number of colors is not limited, therefore it
+      can be used to make a monochrome, bi-color or even a full RGB display.
+
+      Individual LEDs can be addressed in the matrix by their row and column
+      position. The index (0,0) is located in the upper left corner. Columns
+      grow from left to right, and rows grow from top to bottom.
+
+Installation
+------------
+
+      QLedMatrix library:
+        qmake
+        make
+        make install (or copy the plugin into "<Qt4 dir>/plugins/designer")
+
+      QLedMatrix example:
+        cd example
+        qmake
+        make
+        ./qledmatrix_demo
