// 健康診断管理 SiteId 513156(実施年度-集計): NumA~NumH(社員集計項目)をNum031~038へ置き換える
// ワンショットスクリプト。設定(LabelText/Unit/TextAlign/NoWrap等)はそのまま維持し、ColumnNameのみ変更。
// EditorColumnHash.General内の配置位置もNumA~H→Num031~038に置換。既存アイテム件数0件を確認済みのため
// データ移行は行わない(ColumnNameはPleasanterの物理列名に直結するため、データがあれば別途移行が必要)。
// updatesite(Mode:full)を使う。--execute指定時のみ実際に送信、指定なければプレビューのみ出力。
