Give every scheduled action an explicit, predictable target model
(Action then Node then Stack then Options then Schedule):
- System Prune now exposes a Node picker and requires a node, so it can
no longer run silently on the default node.
- Vulnerability Scan and System Prune list local nodes only; both run on
the hub-local Docker daemon and reject remote nodes on the backend.
- Restart Stack service discovery loads services from the selected node
via fetchForNode instead of the active or local node.
- Fleet Snapshot shows a read-only "Scope: Entire fleet" summary.
Backend gains a shared local-node guard and prune node validation on
create and update, plus an executor-level remote-node guard, so the
frontend and backend validation now agree for every action.
