fix(build): provide logging stubs for Lighthouse NPM security scan step

npm.sh uses log_info/log_warn/log_error/log_debug from openshift.sh,
which is normally loaded via _utils.sh. The standalone CI step only
sourced npm.sh, causing 'log_info: command not found' (exit 127).

Define minimal logging function stubs inline before sourcing npm.sh,
matching the fallback definitions in _utils.sh.
