The control plane's image is FROM scratch and runs as 65534, and docker cp keeps
the mode a file had outside — openssl writes a private key 0600 root-owned, so
the copy landed unreadable, secret accept failed with permission denied, and the
CA crash-looped on a root it never got. Chowning it inside the container is not
available: there is no shell in there to do it with.
