Anso 155db30554 fix(blueprints): gate confirmed apply on live intent fingerprint (#1663)
* fix(blueprints): gate confirmed apply on live intent fingerprint

reconcileConfirmedPlan only checked approval_status, so a concurrent compose
edit during Apply could deploy unapproved content under a stale fingerprint.
Match the tick-path fingerprint gate, refuse Apply when live intent drifts,
and surface reconciler refusal as PREVIEW_STALE instead of a false success.

* test(blueprints): cover matching-fingerprint reconcileConfirmedPlan path

Prove the production allow branch still deploys authorized actions when the
approval fingerprint matches, and does not execute unauthorized blast nodes.

* fix(blueprints): report live approval after confirmed snapshot apply

A concurrent edit can clear approval while multi-node snapshot deploy is
still running. Keep the in-flight snapshot contract, but re-read live
effectiveApproval before responding and warn in the rollout dialog when
approval is no longer current.
