Drive rematerialize directly with a group email template carrying a fake
sealed secret: a descendant app gets one copy whose inbound-secret
ciphertext + nonce byte-equal the template's (verbatim copy, no reseal),
the reconcile is idempotent, and reparenting the app out of the subtree
de-materializes the copy.

materialize::rematerialize_stateful_templates reconciles a group cron/queue
template into one app-owned copy per descendant (materialized_from = template),
via the all-apps app_chain CTE ⋈ group-owned stateful templates. A precise
create/delete diff preserves cron last_fired_at on unchanged copies; a queue
copy is skipped-with-warning when the app already fills that queue's consumer
slot (the one-consumer invariant). Called full-live at the route-rebuild
chokepoints: apply (single + tree), app create/delete (apps_api), group
reparent (groups_api) — AppsState/GroupsState gain a pool. Pinned by
tests/stateful_templates.rs (per-app copy, idempotent, new-app materializes,
reparent de-materializes).
