## Summary
- keep stale active operation runs visible in the tenant progress overlay and polling state
- align tenant and canonical operation surfaces around the shared stale-active presentation contract
- add Spec 233 artifacts and clean the promoted-candidate backlog entries
## Validation
- browser smoke: `/admin/t/18000000-0000-4000-8000-000000000180` -> stale dashboard CTA -> `/admin/operations?tenant_id=7&activeTab=active_stale_attention&problemClass=active_stale_attention` -> `/admin/operations/15`
- verified healthy vs likely-stale tenant cards, canonical stale list row, and canonical run detail consistency
## Notes
- local smoke fixture seeded with one fresh and one stale running `baseline_compare` operation for browser validation
- Pest suite was not re-run in this session before opening this PR
