i18n(showcase): 翻译 walker 新采出的 10 个段落标题 (#5405)

`check:i18n-coverage`(仓库级棘轮门)在 CI 抓到 showcase 未译声明串
451 → 461:新增的 `section` kind 把段落标题纳入覆盖面后,showcase
声明支持 zh-CN 却没有这些译文。门要的是译文,不是豁免 —— 基线与
`supportedLocales` 均未改动。

zh-CN 新增 10 条,均为既有体例:

  showcase_task._sections   —— task.view.ts 三个表单投影的段落名
    overview 概览 / schedule 排期 / details 详细信息
    step_basics 基本信息 / step_assign 指派 / step_schedule 排期
    split_task 任务 / split_schedule 排期

  showcase_semantic_zoo._sections —— ADR-0085 fixture 的两个 fieldGroups
    basics 基本信息 / money 财务信息

后者按 `showcase_inquiry` / `showcase_business_unit` 的先例,只加
`_sections` 块(该对象本无 zh-CN 块,其余债务留在冻结基线内)。
`money` 取「财务信息」以贴合分组自己的 description(Financial
fields),而非直译 Money。

`en` 不加条目:默认语言由内联 label 满足,复述源串只会伪造覆盖率。

check-i18n-coverage: OK (12 config(s), 660 baselined untranslated
string(s), none new) —— showcase 精确回到 451,零 missing-section。
