fix(platform-objects): 21 zh-CN metadata-form leaves say what their source says

The 613 LEGACY-TRUSTED zh-CN leaves in `zh-CN.metadata-forms.generated.ts` — differing
from `en`, carrying no digest — were imported from a pre-consolidation hand vocabulary in
`e0077ea36` and never reconciled against the seeded English. The census on #14587 read all
613 and found 26 that assert something the source does not, or drop a distinct concept the
source names. Five (the whole `dashboard` subtree) landed in `9f57f1e31`; these are the
remaining 21, verified still wrong against `origin/main` `9f3989771` before any edit.

No instrument here can see them, by construction: `check-i18n-stale-fill` detects a byte
copy of a previous source revision, and these are hand-written mistranslations. Merge does
not correct them either — it fills gaps only.

Each replacement is argued against this bundle's own usage rather than freshly invented:
`action.fields.body.helpText` takes the sibling `hook.fields.body.helpText` verbatim for
the identical source sentence; 「环境助手」 is the bundle's own rendering of "ambient
assistant"; 「请求体结构」 is its own for "request shape"; 「按对象 / 按字段」 comes from
the two fields the permission section holds; 「分块」、「维度」、「度量」 come from the
report subtree; and the no-trailing-period register follows 60 of 66 translated section
descriptions.

zh-CN only. es-ES and ja-JP are not touched, nor are the 18 looser paraphrases the census
deliberately excluded.

+fix(platform-objects): 21 zh-CN metadata-form leaves say what their source says
+
+`zh-CN.metadata-forms.generated.ts` carries 615 leaves that differ from `en` and hold no
+digest in `zh-CN.source-hashes.generated.ts` — LEGACY-TRUSTED values carried in from a
+pre-consolidation hand vocabulary (`e0077ea36` deleted a 746-line
+`src/metadata-translations/zh-CN.ts` and imported its strings) and never reconciled
+against the English the same commit range seeded. A census of all 613 (as the population
+then stood) found 26 that assert something the source does not, or drop a distinct concept
+the source names. Five of the 26 — the whole `dashboard` subtree — landed in `9f57f1e31`.
+These are the remaining 21.
+
+They are not stale fills and no gate can see them: a stale fill is a byte copy of a
+previous source revision, detectable by cross-locale agreement or a recorded digest, and
+these are neither. Nor does re-extraction correct them — bundle merge fills gaps only, and
+a present-but-wrong leaf is not a gap.
+
+Three defect kinds, all decided against this bundle's own usage:
+
+- **Asserts an input that does not exist.** `skill.sections.triggers.description` promised
+  「触发关键词」 for a section holding only `triggerConditions` (`triggerPhrases` was
+  removed with the key); `email_template.fields.variables.helpText` promised a per-variable
+  「默认值」 that `EmailTemplateDefinitionVariableSchema` does not declare;
+  `action.sections.advanced.description` promised 「批量」 after `bulkEnabled` was removed
+  from that section.
+- **Names the wrong technology.** `action.fields.body.helpText` said the body is
+  「JavaScript 代码」; an L1 expression is not JavaScript. It now reads
+  「L1 表达式或 L2 沙箱 JS 体」 — verbatim the sibling `hook.fields.body.helpText`, which
+  translates the identical source sentence correctly.
+- **Drops a distinct concept the source names.** `object.fields.isSystem.helpText` dropped
+  「共享默认为公开」; `view.fields.filter.helpText` reduced a sentence about the shared
+  visual builder to 「筛选规则」; `permission.sections.identity.description` dropped both
+  sentences explaining how permission sets stack on profiles.
+
+zh-CN only: es-ES and ja-JP are untouched here. The 18 looser paraphrases the census
+excluded are also untouched.
