fix(i18n): review the 64 non-pt-BR dashboard catalogs for translation quality

[diegosouzapw]

Summary

Third of the three final i18n adjustments (_tasks/superpowers/plans/2026-09-16-i18n-completion.md, addendum 2026-09-17): the quality review that pt-BR received in #13885 applied to the 64 other dashboard catalogs. scripts/i18n/review-locale.mjs compares every leaf changed since the locale's last translation commit against its English source and asks the translation backend (LAN OmniRoute, codex/gpt-5.6-sol-low) for a corrected value where meaning, placeholders, register or product terminology are off.

Metric	Value
Locales reviewed	64 (all except en, pt-BR)
Leaves reviewed	41 pre-expansion locales: only leaves changed by the retranslation (#13782); the 24 locales added in 2026-09 (#13044 / #13660 / #13727): every leaf, 13,133 each
Corrections applied	75,263
Reverted afterwards	1,677 — the "correction" replaced a real translation with the plain English term (Host, Proxy, Endpoints, Webhooks, Error, …); the real-translation ratio gate counts those as untranslated and ha/ig/my/phi went red, so the pre-review value was restored for that class in every locale
Net	73,586 corrections
Wall clock	15 h 35 with 6 workers (12:23 → 03:58)
Reports	_artifacts/i18n-review/<code>.md per locale (key / en / before / after), not committed

review-locale.mjs hardening (found by the run, each with a unit test)

• Per-batch retries with backoff (withRetries, 4 attempts, 2/10/30 s); a batch that still fails is skipped and listed in _artifacts/i18n-review/<code>.skipped.json instead of killing the run through main().catch. Before: one upstream hiccup lost the whole run (Amharic: 2 h 42).
• Checkpoints: the catalog is written every 25 batches, not only at the end.
• Dotted leaf keys: 36 leaves of en.json carry a dot in their own key (compliance.eventTypes["apiKey.ban"]); the flattened id was descended naively and the review crashed with Cannot set properties of undefined (setting 'ban') after two hours (Hausa ×3, Greek, Estonian). setDeep now prefers the longest existing key at each level.

Base merge note

Merging release/v3.8.51 (49 commits) into the branch conflicted on 24 catalogs; resolved with a 3-way key merge (base / review / tip): 931 leaves new on the tip taken as is, 63,420 review corrections kept, 12 leaves changed on both sides resolved in favour of the tip. The tip itself is red on i18n:check-keys: #13670 (allowAutoCombos, merged 2026-09-17 21:53 UTC) added 14 settings.* keys to en.json and to no other catalog, so 64 locales miss them. This PR adds and translates those 14 × 64 leaves (sync-ui-keys --translate-markers) so the gate is green again after merge.

Validation

Check	Result
npm run i18n:check-ratio	OK — 65 locales within baseline (+0.5)
npm run i18n:check-keys	OK — 65 locales carry all 13,133 keys, none extra
i18n:check-glossary zh-CN / zh-TW / ko	PASS (provider term normalised after the run)
i18n-placeholder-parity, feature-flag-description-icu-parse-12505, dashboard-localization-contract, server-owned-tool-loop-flag, i18n-home-recent-requests-topology-legend, i18n-cli-namespaces, i18n-key-completeness, i18n-review-locale	66/66
prettier on the 64 catalogs	clean

No production code touched (src/i18n/messages/**, scripts/i18n/review-locale.mjs, its test, changelog fragment).

⚠️ base-red inherited: #14004 (env-doc-sync, xKiro). All 7 reds of the CI run reproduce on the pure base tip 1603c86e in a detached worktree outside this branch, in files this PR does not touch: Docs Gates = the #14004 env/doc contract; check-api-typecheck (codex-responses-ws/route.ts TS2339 7→12, glmResetCards.ts TS2322 0→1, src/sse/handlers/chat.ts TS2345 0→1); the file-size fast gate (tests/unit/chatcore-translation-paths.test.ts 3448 lines on the tip > frozen 3447); and 24 unit test files (body-timeout-integration, chat-managed-lease-routing, chat-route-coverage, chatcore-translation-paths, check-env-doc-sync, compression/{body-adapter,pipeline-integration,rtk-code-stripper,rtk-engine,strategySelector}, error-public-boundaries-hardening, g13-combo-chatcore-golden, gen-budget-card-svg, hard-session-lease-bypass-inventory, issue-7793-env-doc-sync-repro, lib/rate-limit-maxwaitms-disable-execution, provider-limits-local-apikey-sync-spacing, provider-translate-path-golden, providers-constants-split, responses-active-stream-custom-tool, sse-stream-buffer-bytes, stream-markdown-token-boundary, streaming-reasoning-dedup-5786, webpack-create-require-warning), each failing on the tip with the same test names.
