fix(dataset): translate image parse node response

[c121914yu]

What changed

• Use the chat:image_parse translation key for the image parsing child node response in dataset search.
• Add Simplified Chinese, Traditional Chinese, and English translations for the node name.
• Update dataset search and Agent dataset search assertions while keeping billing usage names under account_usage:image_parse.

Why

Chat and app debug pages do not load the account_usage namespace. The image parsing child node response used account_usage:image_parse, so its node name was rendered as an untranslated key.

Impact

Image parsing child responses now display a localized node name in chat details and workflow debugging. Billing labels are unchanged.

Validation

• node scripts/test/withMongo.mjs pnpm --dir packages/service test test/core/workflow/dispatch/dataset/search.test.ts test/core/workflow/dispatch/ai/agent/sub/dataset.test.ts
• 2 test files passed, 10 tests passed.
• Commit hooks passed ESLint and Prettier.
