The dev maestro container's data root is /data/.dcntrlized
(XDG_DATA_HOME=/data), but bind-mount sources are resolved on the daemon's
host namespace — a nonexistent /data/.dcntrlized/... source made Docker
create empty directories, so the auth hub saw /dcntrlized/pki/tls.crt as a
directory and TLS setup failed. DCNTRLIZED_HOST_DATA_ROOT (compose-injected,
/home/franciscofadigas/.dcntrlized) is now substituted for the container-internal prefix when
building identity bind sources. hostBindSource leaves paths unchanged on host
installs.
