chore(i18n): 重生成 platform-objects 的四个翻译 bundle (#5271)

PM 返工第 2 轮。`api` 进 metadata type registry 后,platform-objects 的
metadata-forms bundle 键集多出该类型的 label/description,四个 locale 漂移。

`node scripts/check-i18n-bundles.mjs --write`(merge 模式:不覆盖任何既有翻译,
新键以源文填充)。delta 纯属本单 —— 四个 bundle 各 +4 行,只有 `api` 一个键:

    api: { label: "API Endpoint", description: "Declarative HTTP endpoint — …" }

非英文 bundle 里这两条暂为英文源文,这是 merge 模式的既定产物("they still
need translating");`check:i18n-coverage` 的冻结基线未被突破,故两门皆绿。
手改 `.generated.ts` 不是这条链的修法。

⚠️ 这是我第三次漏门(liveness → docs → i18n),根因是我一直按"改了哪个包就跑
哪个包的门"收工,而这三道都是**仓根**的、由被改内容触发而非由被改目录触发。
已改为按 `.github/workflows` 的 job 清单逐条过:本次 push 前跑完 44 道 CI 必跑
门(lint.yml 25 道 + spec-liveness-check.yml 4 道 + spec 生成物 13 道 +
validate-deps.yml 2 道),全绿。

注:i18n 两门必须在 **full build 之后**跑 —— 抽取器经 extract config 读
`@objectstack/spec` 的 dist、并跑构建后的 CLI。未构建时它报的是九个包
"extract failed — no output",很容易被误读成配置坏了而不是缺构建。
