Unraid Container Builder creates directories at mount points by default,
which fails when the container already has a file at that path. Moving
000-default.conf from a bind-mount to a COPY in the Dockerfile avoids
the OCI runtime error and is the correct pattern — config files belong
in the image, only persistent data should be mounted as volumes.
