fix(coverage): Explicitly disable STRIP_ALL during coverage runs

Added -DDEMO_STRIP_ALL=OFF to cmake configuration in gen_coverage_report.sh
to ensure all test code is included in coverage analysis.

Previously the script relied on the default value of STRIP_ALL, which
could potentially exclude test infrastructure code from coverage reports.

The remaining warnings in coverage output are benign lcov/genhtml warnings
about unknown categories and data inconsistencies, normal for coverage analysis.

Coverage: 57.8% lines, 76.0% functions (77 source files)
