Emit T03 replay fixtures from the published package

Two real DecisionEnvelopes in examples/secrets-engine/replay/ for
secrets-engine to verify its digest join unchanged: a plain allow
(rotate, empty context) and the dual-control allow (destroy with a valid
approval-claim).

Both are included deliberately. input_claim_digests.context appears only
when the request carries a non-empty context, so a consumer asserting the
field is always present would pass on destroy and fail on rotate. One
fixture would have hidden that.

request_digest, policy_package_digest, registry_snapshot_digest and the
context claim digest are verified identical across two runs and are the
fields to pin. id, decision_time and the lifetime bounds move with the
clock; the README says so rather than leaving a consumer to discover it
by flake. lifetime.ttl is 15m from the package allow_ttl.

Emitted from flex-auth/local in standalone mode, not from a cluster pin.
T03 is progress, not done -- it closes when secrets-engine confirms their
validator accepts the records unchanged.
