The 'Dashboard endpoints' list was half-migrated: newer routes were
documented under /api/* but the older ones (approve, deny, the
rebuild/kill/restart/start/destroy lifecycle group, purge-tombstone,
answer-question, cancel-question, request-spawn, update-all, op-send)
were still listed bare. The dashboard FE calls all of them under /api/
since the route migration, so the doc was stale. Prefix the bare entries
(plus the two inline references) to match what the FE actually requests.
Documentation-only; no behaviour change.
