fix(i18n): compose the AI-model diagnostics summary client-side (#2886)

[os-zhuang]

Closes #2886.

CloudAiModelStatus rendered report.summary verbatim — the most prominent line on the panel, in English for every locale.

What reading objectstack-ai/cloud settled

The issue left two questions open. Both now have definite answers.

1. The server does not localize it — and cannot, as currently built.

service-ai/src/effective-model.ts:117:

const summary = `build/ask uses ${input.conversational ?? 'unknown'} (${pinnedNote}); structured uses …`;

A hard-coded English template literal, no locale parameter. And service-ai/src/routes/ai-routes.ts:395:

handler: async () => {
  const report = opts.getEffectiveModel?.();
  return { status: 200, body: report };
}

The handler takes no request argument, so it cannot read Accept-Language even though createAuthenticatedFetch has been sending it since #1319.

2. No server change is needed anyway.

Every ingredient of the sentence is already in the structured payload:

summary clause	field
build/ask uses X	conversational.model	✅
(pinned by … / code default)	conversational.source	✅
structured uses Y	structured.model	✅
(same as build/ask)	structured.pinned	✅
Routing policy: free → A, paid → B	routing.{free,paid}	✅

The issue proposed "return structured data instead of a whole sentence" as the better path. The server was already doing that — the client just wasn't using it. So this is client-only, and doesn't wait on cloud scheduling.

sourceLabel() already produced exactly the clauses the server hand-rolls — pinned by X, code default (no env override), and same as build/ask for an unpinned structured model — so no new source vocabulary was needed.

A dropped diagnostic, not just untranslated text

The client's EffectiveModelReport never declared routing, which the server has always sent conditionally. Its only appearance anywhere was inside the English summary string — so non-English admins could not see the plan→model routing policy at all. That's a diagnostic lost at the type layer, not a translation gap. Now declared and surfaced.

Also fixed: attributeSource emits the bare token 'unknown' when the adapter can't report a model, and sourceLabel fell through to rendering it raw.

Verification

• Full suite: 7,835 passed, 24 skipped, 0 failed.
• turbo build: 44/44.
• Panel tests: 5/5, and mutation-tested — restoring <p>{report.summary}</p> fails four of the five.
• ESLint on the changed areas: 0 errors.
• Four keys added to all ten packs, so the full-parity guard from feat(i18n): complete the locale backfill — all ten packs reach full key parity (#2872) #2909 stays green.

The panel had no test coverage at all before this.

Note

Worth flagging from the process: my first test passed <I18nProvider language="zh">. That prop does not exist — it's silently ignored at runtime, so the zh render produced English. My own "zh must differ from en" assertion caught it; the fix was createI18n({ defaultLanguage }). tsc would also have rejected it, vitest would not — the same gap that motivated #2911.
