test: respect GitHub ACTIONS_STEP_DEBUG for verbose test logging

When GitHub Actions step debug logging is enabled via ACTIONS_STEP_DEBUG,
bypass both general log suppression (setLogLevel) and intentional error
suppression (mmTestMode checks) to provide full diagnostic output for
debugging test failures.

This maintains clean test output in normal CI runs while enabling
verbose logging when explicitly requested via GitHub's "Re-run jobs
with debug logging" feature.
