Joseph Doherty 75e559f6d8 fix(acl): filter Server-object (i=2253) event subscriptions per event through the data-plane ACL (#586)
Server-object (all-events) items bypassed the ACL entirely: the SDK attached them to every root
notifier's fan-out via SubscribeToAllEvents, and a root notifier with no direct subscriber forwarded
to the core Server object, which this node manager never sees.

- SubscribeToAllEvents override records the item and attaches it to nothing.
- Each condition's own OnReportEvent (fires once per event) queues the event to each recorded item
  whose session holds Subscribe on the condition (RawPath) or any notifier folder it reports through
  -- the per-folder path's question; otherwise mirrors MonitoredNode2.OnReportEvent.
- The root-notifier forward to the core Server object (OnReportEvent override) is dropped.
- ConditionRefresh on an i=2253 item is filtered the same way (once per condition).
- Revalidation is implicit: every event re-asks the authorizer (per-generation cache, key expiry and
  revocation re-checked per call). Inert with Security:Acl:Enabled=false.

Over-the-wire tests: no-grant vs granted (positive control), created-before-deploy, revoke/restore by
deployment, key expiry with no tick, refresh, and flag-off. Falsified: disabling the filter, or
restoring the forward, turns the enforcement tests red.
