Fix three image cleanup gaps: weekly restart prune, mode-aware rebuild error, monthly orphan sweep

docker_weekly_restart.sh was missing the trailing dangling prune that daily_restart has.
docker_update.sh rebuild failure message always named docker_daily_restart.sh regardless of mode.
docker_prune_images.sh --all added to monthly — the only scheduled path that removes tagged orphan images.
