docs/security.md gains the canonical table of per-driver namespaces, the five
enforcement seams, the out-of-scope cases (appsettings ${secret:}, Sql
connectionStringRef) and the migration steps for existing configs. Galaxy,
OpcUaClient, Heidenhain, Configuration and driver-specs docs, the Galaxy
options XML docs, the drivers rule file and the docker-dev compose comment
point at it. docker-dev's env:GALAXY_MXGW_API_KEY stays valid (allowed legacy
prefix), so no rig change is needed.
