- wheel_date_picker.dart 重构为统一组件：单日期 showDsDateDropdown（面板= 可输入框+三列滚轮+今天/确定）、范围 showDateRangeDropdown（起始|结束双窗格 并排+共用底栏）；桌面锚定下拉（透明遮罩不冻结窗口）、窄屏底部 sheet 同内容 （范围纵排）——同一套窗格两端复用 - 扁平化：输入框与滚轮同宽 248、文字水平垂直居中(mono)、去掉全部阴影/立体 效果（滚轮外框仅 1px 边框，中心高亮带去描边） - DsDateCell（录单日期格）与 DatePickerField（登记收支）改为触发器：点选/ 回车打开统一面板，键入在面板内完成；出库工具栏时间 chip 补切到新组件 - 旧 showWheelDatePicker/showWheelDateRange 两步弹窗删除；组件测试改写为 新契约（触发器+面板键入+词法归一），表单 golden 随形态更新 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
