Aleksei Sviridkin 6498d37be7 fix(security): run first-party scratch images as non-root UID 65532
CodeRabbit (PR review on #2494) flagged that the first-party scratch
images leave the container process running as root because no USER
directive is set. Adds the standard distroless nonroot UID/GID
65532:65532 just before ENTRYPOINT in seven first-party Dockerfiles.

The chosen UID matches gcr.io/distroless/static:nonroot and the
existing convention in the kubevirt-csi-driver and kamaji images.
Statically-linked Go binaries copied with default permissions remain
world-readable, so they execute fine under the non-root identity
without an extra chown step in the builder stage.

Touched:
- packages/system/backup-controller/images/backup-controller/Dockerfile
- packages/system/backupstrategy-controller/images/backupstrategy-controller/Dockerfile
- packages/system/cozystack-api/images/cozystack-api/Dockerfile
- packages/system/dashboard/images/token-proxy/Dockerfile
- packages/system/flux-plunger/images/flux-plunger/Dockerfile
- packages/system/kubeovn-plunger/images/kubeovn-plunger/Dockerfile
- packages/system/lineage-controller-webhook/images/lineage-controller-webhook/Dockerfile

Vendored Dockerfiles (kubevirt-cloud-provider, redis-operator,
keycloak-operator, linstor-csi, multus-cni, objectstorage,
s3manager, kamaji, cluster-autoscaler) are intentionally left
untouched — their runtime user choice is upstream's call.
