Pin tenant-engine to the CI-built digest from 7e68cc8, record rollback
digests, and close T05 after live create/update/retire/replay/reactivate
evidence against a disposable production tenant. Hands the 0.1.0 contract
to USER-WP-0021.
Production still serves the TEN-WP-0004 image, which has no lifecycle
routes. Recover the live railiance01 objects into deploy/ so rollback
does not depend on a cluster annotation, and add the fleet CI image
workflow so the lifecycle image is built from a forge revision.
