MOAD-0004 (Logged Secret / CWE-312): CLEAN

Searched blenkernel/, editors/, render/ for credentials (token, api_key,
password, auth) in CLOG_* and printf calls. Blender does not have built-in
render farm API key or cloud credential logging paths in the C/C++ core.
Network render (Flamenco) is a separate service; credentials are not handled
in the blenkernel/editors source tree. No CWE-312 defect found.
