/// 入/出库单行内操作按钮，列表表格与移动端卡片、入库与出库两屏共用。
///
/// 此前 stock_in / stock_out 各自逐字重复了「详情/打印/结清/修改/删除/提交/通过/拒绝」
/// 的状态门控（draft/pending/approved）与 WriteGuard 包裹脚手架，仅单据类型、路由、
/// 打印函数与回调不同。这里把**相同的结构**收敛到单一来源，差异通过回调注入：
///
///   - [afterPrint]：紧随「打印」之后的附加按钮（入库的「打标签」；出库传空）。
///   - 各 `on*` 回调由调用方绑定到对应单据的确认/跳转逻辑。
