CHW-4928 OrgDeleteSimulateExpired

simulate snapshot stale; re-run --dry-run

Default message: simulate snapshot stale; re-run –dry-run
HTTP status: 409 (client)

Problem. chainsaw org delete --simulate-id <id> --confirm (or the equivalent DELETE) was refused. Cause. The simulate_id either fell past its 5-minute TTL since the preview, or refers to a different org than the one being deleted. The W0 safety gate deliberately keeps the window tight so a stale preview can’t authorize a hard delete against a drifted inventory. Fix. Re-run chainsaw org delete --dry-run (or POST /api/orgs/{id}/delete/preview), review the fresh inventory, and re-submit with the new simulate_id. HTTP 409.
