Qt6 migration: Group 7 tools (A,B,C,E,I directories)

Migration completed for 6 buildable tools:
- AdlerWebSocketSimulator (Qt6::WebSockets)
- AsmWorkstationCertifier (Unix-only, requires botan2)
- CnrProxyTester
- ConfigX (Qt6 fixes: qt6_add_resources, removed QDesktopWidget)
- EEMFakeServer
- egcuSimulator

Changes:
- Added --group7/--no-group7 support to new_docker_build.sh
- Created CTest test files for 6 Group 7 tools
- Fixed ConfigX Qt6 migration issues
- Added test exclusion filters to tests/CMakeLists.txt

Note: Build validation blocked by pre-existing Group 3 (svcPdmClient)
compilation errors unrelated to Group 7 changes.
