docs+test(hierarchies): end-to-end review follow-ups (M5/M6/M7)

Findings from a 3-lens end-to-end review (correctness, security, tests).
Security review came back clean (cross-repo authz sound, isolation intact,
M5 gate sound modulo the documented manifest-trust boundary). No behavior
changes here — only accuracy + coverage:

- apply_service Phase B2: correct the descendant-expansion comment. The chain
  is COMMITTED ancestry (ancestors() reads the pool), so a reparent in the same
  apply takes effect next apply — same "one more apply" shape the in-tree path
  and group-create reparenting already have. Authz stays sound: the gate and the
  expansion consume the SAME chain (checked == written).
- doc §4.5: document the two known "one more apply / no data risk" limitations
  — reparent-in-same-apply template resolution, and the `{env}` source split
  (declared apps use --env; cross-repo descendants use apps.environment).
- approval journey: give the app real (`[vars]`) content so the editor member's
  AppVarsWrite is actually exercised — the admin-gate test now proves approval
  is ABOVE editor-write, not just "any non-admin is refused". (Vars cascade with
  the app; scripts are ON DELETE RESTRICT and would break AppGuard teardown.)
- templates journey: assert descendant expansions are idempotent (stable row
  ids on re-apply — no churn), matching the in-tree guarantee.

--- descendant of this group runs the ancestor's `audit` template." Until now
--- only an app could suppress; a group could not.

--- Reshape `template_suppressions` to a POLYMORPHIC owner, exactly like the

---   * `app_id`   — made nullable; the exactly-one CHECK enforces app XOR group.
---   * the per-app unique index becomes per-owner partials.
---
--- A GROUP suppression declines a template the group INHERITS from a higher
--- ancestor, for the group's whole subtree. Inheritance-only still holds: the
--- dispatch filters gate to group-owned rows, and a suppression only matches on
--- the suppressing owner's ancestor chain — a group can decline what it

--- by the OWNING GROUP's chain and runs the handler under the WRITER app
--- (`cx.app_id`) — the same "group template runs under the firing app" model.

--- unchanged dispatch paths (scheduler, queue consumer, email webhook) only ever
--- see app-owned rows.
---
--- `materialized_from` links a managed app-owned row back to the group template

-//!
-//! A group-owned cron / queue / email trigger is a TEMPLATE that is never
-//! dispatched directly (the scheduler / queue consumer / email webhook all
-//! filter `t.app_id IS NOT NULL`). Instead this reconciler expands each template
-//! into an app-owned copy — `materialized_from = template.id` — for every
-//! descendant app, and removes copies whose (app, template) pair no longer
-//! inherits. The copy owns its per-app state (cron `last_fired_at`, the queue
-//! advisory lock), so the unchanged dispatch paths work against it as if it were
-//! hand-authored. An EMAIL copy is a verbatim byte-copy of the group template's
-//! sealed inbound secret — the group resolved + sealed it against its own store
-//! once at apply (shared-group-secret model), and email secrets are v0/no-AAD so
-//! the ciphertext is portable across rows; no master key is needed here.
-//!
-//! Full-live like `rebuild_route_table`: called at the same chokepoints (apply,
-//! app create/delete, group reparent). A precise create/delete diff (not
-//! delete-all-then-recreate) preserves `last_fired_at` on unchanged cron copies.
-//!
-//! Returns per-app WARNINGS (e.g. a queue whose consumer slot is already taken)
-//! — the caller surfaces them; materialization of the other pairs still
-//! proceeds.

-//! app that declares a `[suppress]` for both references STILL fires the trigger
-//! (dispatch anti-join skips a sealed row) and STILL serves the route
-//! (rebuild-time skip is gated on `!sealed`). The gate is exactly `sealed`: an

-//! §11 tail integration test: per-app opt-out of inherited group templates.
-//! An app that declares a suppression must NOT match the inherited TRIGGER
-//! (dispatch anti-join) nor serve the inherited ROUTE (rebuild-time skip); a
-//! sibling app with no suppression still inherits both. Suppression is
-//! inheritance-only — an app's OWN trigger on the suppressed handler still
-//! fires.
-//!
-//! Deterministic: drives `list_matching_kv` + `list_effective` /
-//! `compile_effective_routes` directly (no async dispatcher). Skips cleanly
-//! when `DATABASE_URL` is unset.
