fix(platform-objects): the zh-CN dashboard gap help text says what its source now says (#16163)

* fix(platform-objects): re-translate the zh-CN dashboard `gap` helpText its source moved out from under

`metadataForms.dashboard.fields.gap.helpText` read 「栅格间距（Tailwind 单位）」 — a
faithful translation of `Grid gap (Tailwind units)`, which the source no longer says.
`packages/spec/src/ui/dashboard.form.ts:25` now reads `Space between widgets, in steps
of 0.25rem (4 = 1rem)`: it dropped the framework unit an app author cannot act on and
gained a magnitude the author can compute with.

The leaf kept the retired vocabulary and never gained the magnitude, because bundle
merge fills gaps only — a present-but-stale leaf is not a gap. Now
「组件之间的间距，每级 0.25rem（4 = 1rem）」: `widgets` is 「组件」 as everywhere else in
this bundle, the grid framing is gone as it is upstream, and the conversion is carried
so a zh author can size `gap` without reading the English.

One leaf. `columns` is deliberately unchanged upstream, so 「栅格列数（默认 12）」 stays
accurate, and the rest of the subtree was corrected on 2026-09-03.

+`metadataForms.dashboard.fields.gap.helpText` in `zh-CN.metadata-forms.generated.ts`
+read 「栅格间距（Tailwind 单位）」. That was a faithful translation of the source it was
+extracted against, `Grid gap (Tailwind units)` — but the source has since been rewritten
+to `Space between widgets, in steps of 0.25rem (4 = 1rem)`, which deliberately drops the
+CSS framework unit an app author never chose and cannot act on, and adds the magnitude
+the author can size a dashboard with.
+
+The leaf kept the retired vocabulary and never gained the magnitude, because bundle merge
+fills gaps only: a present-but-stale leaf is not a gap, so no amount of re-extraction
+corrects it. It now reads 「组件之间的间距，每级 0.25rem（4 = 1rem）」 — `widgets` is
+「组件」 as it is everywhere else in this bundle, the grid framing is gone exactly as it is
+upstream, and the conversion is carried so a zh author can size `gap` without reading the
+English.
+
+One leaf. `columns` is unchanged upstream, so 「栅格列数（默认 12）」 stays accurate, and
+the other five leaves of this subtree were corrected separately.
