DOCFIX-170: full-project sweep -- VR0 runbook + OpenTofu doc fixes ...

Part of an 8-dimension parallel sweep for errors/architectural problems
across the whole repo, requested after DOCFIX-169. phase-08-workload-
cluster-acceptance.md had the same cascading-staleness class as DOCFIX-169
(Designate framing never updated after DOCFIX-167's bundle.yaml edit) --
fixed with a nuanced correction distinguishing "charms now active/idle"
from "D-011.8's real acceptance criterion still needs Stage 7's overlay."
Also fixed a stale opentofu/modules/base-image/outputs.tf comment
referencing nonexistent cloudinit-vm variables. Session ledger updated
with the full 8-dimension sweep summary and two orphaned DOCFIX-number
closures (164, 167) caught as integration misses.
