修复：日期录入收口共享层——「今天」快捷键 + 品牌配色 datePickerTheme（M3.5-02）

Browse Source 
用户实测已因日期选择器误录：Flutter 原生日历只给年份网格、月份必须靠 < >
逐月点，从 9 月回 4 月要点 5 次，他把当月（2026-09）的就医记录记成了
2026-04-09，进而误判「本月花费 ¥0」是聚合坏了。

新增 lib/core/widgets/app_date_picker.dart，全仓 7 处裸 showDatePicker 收口
（改造后 lib/ 下 showDatePicker 只出现在该文件内部一次）：

- pickAppDate(...)：calendar 首屏 + 保留头部铅笔切手输；initialDate 自动夹进
  [firstDate, lastDate] 防原生越界断言（调用方常传「当前值 ?? 今天」，而
  「到期日期」的 firstDate 就是今天，历史值可能已越界）；返回值统一抹时分秒；
  中文文案一律交给 zh-CN 本地化，不硬编码，避免两处文案漂移。
- AppDateFieldTrailing(...)：7 处日期行统一「今天 + 日历图标」。今天越界自动
  隐藏按钮、提交中禁用、触控 44×44、primaryStrong 白底 4.49:1。

入口模式取舍：不用 calendarOnly——它恰好会砍掉手输按钮，把「录一个已知日期」
这条唯一快路堵死；也不用 input 首屏——「记今天」这类高频场景敲 8 个数字更慢。
两条路都留着最省事。

「今天」为何放表单行而非弹窗内：原生 showDatePicker 无法注入自定义动作
（builder 只能包裹整个 Dialog，拿不到内部选中态；塞进 Column 还会因 Dialog
在无界高度下贪心布局而溢出）。放表单行反而更快——一键落值连弹窗都不用开，
把容易走错的月份导航整段绕开，且一次实现 7 处形态完全一致。

各调用点原有的 firstDate/lastDate 业务约束原样传入、一字未改（健康事件
不许未来、到期日不许补记过去、疫苗 allowFuture 双态、生日不许未来），
并由 widget 测试直接断言 DatePickerDialog.firstDate/lastDate 防后续悄悄放宽。

顺带修配色：此前从未定制 datePickerTheme，选中日直接吃 ColorScheme.fromSeed
由珊瑚橙派生的暗红棕，与品牌脱节。新增 _datePickerTheme 只复用 05 号规范
（iteration-2/05、iteration-3/05）已审计的色对，不新造色值：头部
surfaceTint + primaryDark 7.98:1（选中 chip 同款）、选中日/年 primaryStrong
实底白字 4.49:1、今日 primaryStrong 1.5px 描边、星期表头 inkSoft 6.59:1、
越界日 muted（DEBT-2 允许的禁用态用途）。headerHeadlineStyle 取 22px
（默认 32）：中文「9月10日周四」在横屏侧栏头部 26px 起就折行。
