Part of #30512 — package 6 of 11, first half
(`@objectstack/service-settings` in `zh-Hant`, `ar`, `fr`, `pt-BR`). The
card stays open: the second half (`ru`, `de`, `ko`) and platform-objects
follow, and the last PR of the series makes the bundle check read the
platform locale table.

## 维护者速读

- **改了什么：** 「设置」里内置的设置页（邮件、短信、品牌、公司、本地化、认证、文件存储、AI 与向量、知识库，以及
`@objectstack/objectql`
注册的数据生命周期页）的页标题和说明、分组、字段名和帮助、选项、提示条、操作按钮和来源标记，补上繁中、阿语、法语、巴葡 4
种。俄语、德语、韩语在下半包。
- **为什么改：** 平台语言表要求每个界面带齐 11 种语言；这是第 3 期按包补齐的第 6 个包的上半。用这 4
种语言的管理员打开「设置」不再看到英文。
- **风险与回滚：** 只加 4 个翻译文件和注册行，不动逻辑、schema、接口；原有 4 种语言一字未改。交接提交里改
`localization-currency-lock` / `localization-locale-options`
文案表的部分**按席位裁决整段去掉**：#30630（已作为 #30734 落地）拥有这两张表，且已带齐 11 种语言。测试改动只是覆盖测试把
4 种新语言加进列表（覆盖变宽，没有放宽断言）。回滚即撤 PR。
- **先看：** `src/translations/index.ts`（按表标签注册，zh-CN 在 zh-Hant 前），再看
`settings-translation-coverage.test.ts`，然后抽看任一新语言文件。
- **两分钟验证：** `pnpm --filter @objectstack/service-settings exec vitest
run src/translations/settings-translation-coverage.test.ts` 全绿。
- **需要你做的：** 无，席位落地。

## What changes

- Four new hand-authored translation modules under the platform locale
table's tags (`zh-Hant`, `ar`, `fr`, `pt-BR`), covering every built-in
settings manifest: page titles and descriptions, group headings, field
labels and help, option labels, banners, action buttons and the source
badges. Country pickers name each country in the reader's language
through `Intl.DisplayNames`, as the existing locales do.
- `src/translations/index.ts` registers them in
`settingsBuiltinTranslations` (`zh-CN` stays ahead of `zh-Hant`) and
exports them beside the existing four.
- Carried from the released handover commit `70f9870a` (session
`session_01Utp6Cai5CRdAs4u9gTipWU`) **without** its
`localization-currency-lock.ts` / `localization-locale-options.ts` hunks
(and their test hunk), per the seat's ruling of 2026-11-05: #30630,
landed as #30734, owns those copy tables and already carries all eleven
languages there. This PR does not touch them.
- The `zh-Hant` file writes the Chinese provider brands in Traditional
script (`阿里通義`, `矽基流動`, `智譜`); the handover had kept the Simplified
spelling.

## Tests

- `settings-translation-coverage.test.ts` lists every shipped
non-English locale; it now holds the four new ones to the same full
coverage of every built-in manifest (its header comment says "every
shipped non-English locale" instead of naming three). No assertion
changed.

## Acceptance notes

- **Quality bar (#17508 / PR #19345):** every leaf written for the
reader; placeholders, code spans, URLs and identifiers byte-identical,
checked mechanically per leaf against `en` and against `zh-CN` (which
carries the inline-manifest keys `en.ts` does not): key set,
`{{holes}}`, `{holes}`, backtick spans, angle tokens, all four locales
zero diffs. Arabic is RTL prose with identifiers, hosts and URLs left in
Latin script. `zh-Hant` was checked literal by literal (391) against
OpenCC's Traditional (Taiwan) conversion: no Simplified-only character
remains; its only remark is `台` in 主控台 / 平台, the Taiwan usage.
- **Leaves equal to English, on purpose:** provider, product and
protocol names (`SMTP`, `S3`, `OpenAI`, `Anthropic`, `Vercel AI
Gateway`, `Turso / libSQL`, `RAGFlow`, …); the terms the existing
`zh-CN` / `ja-JP` / `es-ES` also leave in English (`Base URL`,
`Embedder`, `Bucket`, `Backend`, `Endpoint`); words spelled the same in
the language (`fr` `Port`, `Contact`, `Finance`, `Sessions`, `Local`,
`Global`; `pt-BR` `Host`, `Local`, `Global`); and country names whose
local spelling is the English one.
- No cross-locale coincidence: `check:i18n-stale-fill` passes with the
baseline untouched.
- No string opens with `os ` followed by a lowercase word
(`check-cli-command-ids` passes), and the whole "Lint · docs & code
guards" lane was run locally before opening.

The branch is one commit on `main` `a2f523aa` (after #30856 landed). Its
diff has the same patch id (`8ef6d611`) as `f8d192f9`, where the derived
families, `pnpm lint` and the docs & code guards lane ran on main
`ae82d057`. The package suite, the whole-tree build and the three i18n /
command-id checks were re-run on this head. (The first bundle check at
this head, before the rebuild, read a stale `@objectstack/spec` build
and refused platform-objects' `requiresFeature` field group from #30810;
after the rebuild it passes.)

Dogfood: not run — content-only package PR, no `!` in the title and no
`(narrowing)` arm.

+i18n(service-settings): the built-in Setup settings pages ship in Traditional Chinese, Arabic, French and Brazilian Portuguese
+
+Clause-②: no
+Metadata-protocol: none
+
+The built-in settings pages (Mail, SMS, Branding, Company, Localization, Authentication, File Storage, AI & Embedder, Knowledge, and the Data Lifecycle page `@objectstack/objectql` registers) now carry `zh-Hant`, `ar`, `fr` and `pt-BR` beside the existing `en`, `zh-CN`, `ja-JP` and `es-ES`: page titles and descriptions, group headings, field labels and help, option labels, banners, action buttons and the source badges. An administrator reading Setup in one of those languages sees these pages in their own language instead of English. Country pickers name each country in the reader's language through `Intl.DisplayNames`, as the existing locales do. The settings coverage test now holds each new locale to the same full coverage. First half of package 6 of #30512; `ru`, `de` and `ko` follow in the second half.
