Fleet-wide fix matching the vm-db precedent (e3a0ab5). In all-mode autoheal
restarts ANY container Docker marks unhealthy, so a healthcheck that blips
under load (redis-cli ping timing out) triggers an endless restart loop of a
healthy container -- observed on docs 2026-08-14 (paperless-redis +
docs_watchtower). Opt-in heals only containers labelled autoheal=true; real
crashes stay covered by restart: unless-stopped.
