+ * POST /api/onboarding/[id]/dismiss
+ *
+ * Customer-side acknowledgement of a rejected or cancelled request
+ * (Bug 13). Sets `dismissed_at = now()` so the row stops appearing
+ * in the dashboard's `listActiveTenantRequestsByOrgId` query. The
+ * row itself is preserved for audit.
+ *
+ * Authorization mirrors the GET / DELETE / PATCH endpoints on this
+ * resource: customer owners (or platform staff) of the row's org.
+ *
+ * Idempotent: dismissing an already-dismissed request returns 200
+ * with no change. We refuse to dismiss non-terminal rows (pending,
+ * approved, provisioning, active) — those are still actionable, and
+ * "hiding" them would stash live state from the customer.
