fix(spec): localise the column heads of the view Columns, Sort and Tabs tables (#19968)

Fixes #19955
Clause-②: no

This is the localisation follow-up the maintainer asked for, in the
shape #17508 ruling A settled. PR #19917 gave the row items of the
`view` `columns`, `sort` and `tabs` repeaters English titles.
`view.form.ts` enumerated no row children for them, so Studio showed
those titles untranslated in `zh-CN` / `ja-JP` / `es-ES`.

- `packages/spec/src/ui/view.form.ts`: the three repeaters enumerate
their row children. Each `label` equals the item schema's own `.meta({
title })`; the dev compared them on the built dist.
- The four metadata-forms catalogs: the generator emitted the `en`
leaves; `zh-CN`, `ja-JP` and `es-ES` are AI-authored, reusing the
catalog's existing renderings where one exists. The dev report
`5813748776` lists every reused and invented rendering.
- `repeater-row-properties.test.ts`: `view` moves inside the derived
population, so its no-`en`-echo case covers the new leaves. The dev
ablated it red.
- `object-lifecycle-panel-echo-decisions.test.ts`: the translated-label
positive control moves by exactly the rows that landed, as its comment
prescribes. The seat extended the claim to this file (`5813775189`).
- Changeset: `@objectstack/spec` and `@objectstack/platform-objects` at
`patch`.

The `view.columns` union renderer question is carried as
objectstack-ai/objectui#10239.

+Studio's view property panel names the columns of its Columns, Sort and Tabs tables in the author's language, not only in English
+
+Clause-②: no
+
+`view.form.ts` now enumerates the row properties of the `columns`, `sort` and `tabs` repeaters, each with a `label` equal to its item schema's own `.meta({ title })`, so `os i18n extract` emits a `metadataForms.view.fields` key for each row property. The `en`, `zh-CN`, `ja-JP` and `es-ES` platform catalogs carry those keys. The translated catalogs reuse the word they already use for the same concept where they have one (`Label` → 显示名称 / 表示名 / Etiqueta, `Direction` → 排序方向 / 並び方向 / Dirección).
+
+The row children declare no `type`, so each row input's widget is still derived from the schema. The view schema itself is unchanged.
