feat(historian): OPC UA HistoryUpdate in the node manager + HistoryUpdate authorization (T6)

- OtOpcUaNodeManager overrides HistoryUpdateData / HistoryDeleteRawModified / HistoryDeleteAtTime,
  block-bridging to the optional IHistorianDataUpdater under the shared HistoryRead batch limiter +
  deadline. Insert/Replace/Update map to HistoryUpdateMode; Remove, IsDeleteModified, events and
  structure data are BadHistoryOperationUnsupported. Per-item codes stitched back in request order
  (MinValue SourceTimestamp => BadInvalidTimestamp, untypeable value => BadTypeMismatch); success
  clears the base's pre-seeded Unsupported error.
- HistoryWrite AccessLevel bit OR-ed in for historized nodes when an updater is wired (raw + UNS);
  it is dispatch-load-bearing in the SDK base. OtOpcUaSdkServer.SetHistorianDataUpdater; the hosted
  service assigns it from an optional HistorianUpdaterHolder before SetSink, clears it on stop.
- AuthorizeHistoryUpdate: ACL on => scoped OpcUaOperation.HistoryUpdate decision (replaces the role
  check); ACL off => #563 key re-check + new OpcUaDataPlaneRoles.HistoryUpdate role, conferred by
  ApiKeyInterimRoleMapper only from a Cluster-scoped HistoryUpdate grant (WriteOperate does not).
- AdminUI ACL editor offers NodePermissions.HistoryUpdate.
