Fix Release 2 build: restore test wiring lost in merge, use Ninja in DEB packaging

The full-module import merge (097e5b488) replaced the validated Release 2
test wiring with the full-tree CMake files, leaving 5 targets referenced by
new_docker_build_release2.sh / README undefined:

- Restore LogViewLogger library in TetraIF/LogView/CMakeLists.txt
  (pre-merge file defined both LogViewLogger lib and LogView exe)
- Re-add ADD_SUBDIRECTORY(unit-test) in TetraIF/CMakeLists.txt
  (coprtcnv_unit_test, logview_unit_test, prtcnv_unit_test)
- Add CommonUnitTestsPlaceholder to Lts/Common/CMakeLists.txt (MockCoordTrans)

Driver (new_docker_build_release2.sh):
- Pass -DBUILD_TESTING=ON: TetraIF/unit-test is gated on BUILD_TESTING
- Default GUEZ_MODE=ON: the DEB step expanded ${GUEZ_MODE} in-container
  where it was unset, producing -DGUEZ_MODE= (false in CMake)

rpmbuild/make_rpm_ubuntu26_release2.py:
- Use the Ninja generator (cmake -G Ninja / dh_auto_configure -GNinja):
  with CMake 4.2.3 in the legatus-qt6:1.0 image the Unix Makefiles
  generator emits no rule for AUTOMOC <target>_autogen/mocs_compilation.cpp
  ("No rule to make target") and every Qt target fails; Ninja handles
  automoc correctly (verified: ninja -n of all 39 Release 2 targets passes)
- Add ninja-build to debian Build-Depends

Verified inside legatus-qt6:1.0 (mount /repo, BUILD_RTI=ON, BUILD_TESTING=ON,
Ninja): cmake configure exit 0 and ninja -n of the full Release 2 target
list (GROUP1/3/5/6, 39 targets) exit 0.
