Folds the good parts of #1412 into this PR and addresses both review-bot reviews (#1412 review 1789, #1414 review 1791): - Everything after the OpenBao store is best-effort. Decode, reconnect, listing and revokes run in reap_superseded(); reap_summary() turns any error into "reap skipped" plus a warning, so rotate_ha_token returns Ok. A failed run would start a second pod (backoffLimit: 1) that keeps the token just stored and its successor and reaps the token consumers still hold until ESO syncs, i.e. the #1081 outage. Two unit tests cover it. - Warn when the replaced token is not named "<client_name> [<6 hex>]": no later run reaps it, so it needs a manual revoke (from #1412). - Staged image rollout (from #1412): only the three HA CronJobs carry the flux-system:secret-rotator marker; the other 17 rotators stay on 2026-07-30 until a manual HA run validates the new binary, then a follow-up adds the marker to them. rotation/kustomization.yaml records the exception. - Merged current main (a6f37e2b,1691a0ac): the Reloader annotations for zone-configurator and speech-to-phrase are already there via #1409.
