fix(platform-objects): the zh-CN dashboard subtree says what its source says

Four more leaves of `metadataForms.dashboard` described the Studio dashboard
property panel in terms `packages/spec/src/ui/dashboard.form.ts` does not use —
each naming a concept the source omits while dropping one it names:

  sections.basics.description   「名称与图标」          -> 「仪表板标识与描述」
  sections.widgets.description  「图表、指标、列表等」  -> 「放置在栅格上的卡片与图表」
  sections.filters.description  「全局筛选与日期范围」  -> 「应用到所有组件的默认筛选与全局筛选」
  fields.header.helpText        「标题、操作按钮与筛选」 -> 「仪表板页眉配置（title、subtitle、actions）」

`basics` promised an icon input, and the dashboard schema declares no icon key
at all (the only `icon` under `dashboard.zod.ts` is per header action) — the
same defect class as the layout leaf this branch already corrected, which
promised a responsive-breakpoint control. The other three swapped which concepts
the section covers: widgets is cards and charts on the grid, not metrics and
lists; filters is default plus global filters across widgets, not the date range
(that is the separate `dateRange` field); and the header carries a subtitle, not
filters.

The replacements reuse this bundle's own established terms and mirror es-ES /
ja-JP, both of which are correct at all five leaves. The two changesets are
consolidated into one so the subtree's correction lands as a single release
note row.

+fix(platform-objects): the zh-CN `dashboard` metadata-form subtree says what its source says
+
+Five leaves of `metadataForms.dashboard` in `zh-CN.metadata-forms.generated.ts`
+described the Studio dashboard property panel in terms the source form
+(`packages/spec/src/ui/dashboard.form.ts`) does not use, each one naming a
+concept the source omits while dropping one it names:
+
+| leaf | was | now |
+| --- | --- | --- |
+| `sections.layout.description` | 「栅格与响应式」 | 「栅格尺寸与刷新间隔」 |
+| `sections.basics.description` | 「名称与图标」 | 「仪表板标识与描述」 |
+| `sections.widgets.description` | 「图表、指标、列表等」 | 「放置在栅格上的卡片与图表」 |
+| `sections.filters.description` | 「全局筛选与日期范围」 | 「应用到所有组件的默认筛选与全局筛选」 |
+| `fields.header.helpText` | 「标题、操作按钮与筛选」 | 「仪表板页眉配置（title、subtitle、actions）」 |
+
+Two of them sent a zh-CN author looking for a control that does not exist.
+`layout` promised a responsive-breakpoint input in a section holding `columns`,
+`gap`, `refreshInterval` and `header`, and left the refresh cadence unnamed.
+`basics` promised an icon input; that section holds `name`, `label` and
+`description`, and the dashboard schema declares no icon key at all — the only
+`icon` under `dashboard.zod.ts` is per header action. The other three swapped
+which concepts the section covers: widgets is cards and charts on the grid, not
+metrics and lists; filters is default plus global filters across widgets, not
+the date range (that is the separate `dateRange` field); and the header carries
+a subtitle, not filters. The replacements reuse terms this bundle already
+establishes — `grid` → 「栅格」, `widgets` → 「组件」, `identity` → 「标识」, and
+the literal key list rendered as `（title、subtitle、actions）` the way
+`page.fields.layout.helpText` renders `（header、main、sidebar、footer）`.
+
+The source strings have not moved since the form was created: all five have been
+byte-identical across that file's only two commits. zh-CN's values were carried
+in from the pre-consolidation `metadata-translations/zh-CN.ts` overlay and never
+reconciled against the extracted English, while es-ES and ja-JP were translated
+from it and are correct at all five. So this is a translation correction, not a
+re-sync after a source edit — nothing else in the bundle, the source form, or
+the recorded source-hash companion changes.
