fix: auto-healer v6 — remove explicit --network flag from rollback (caused network bridge not found)

- rollback was using --network bridge explicitly, which fails on this Synology's
  Docker daemon when the bridge network is associated with a Swarm overlay
- Fixed: omit --network flag entirely, let Docker use default bridge behavior
- Also found and fixed: gateway container on Swarm overlay network couldn't
  route to 192.168.0.11:4014 — attached to bridge network to resolve
