fix: point glossary rows at live i18n keys - #1083

Points the glossary rows whose i18n keys no longer exist at their live keys, and takes each row's values from the new key. The termbase is regenerated from the glossary.

Re-keyed, label unchanged

• Embed Into Site: deployments.studio.accessPoint.embedIntoSite (Access Point Web App card; the Agent card uses agent-v-2.agentDetail.access.webApp.actions.embedIntoSite)
• Unpublished changes: agent-v-2.agentDetail.configure.publishBar.unpublishedChanges (Agent publish bar only)
• Backend Service API: agent-v-2.agentDetail.access.serviceApi.title, the visible card title on Workflow, Chatflow and Agent apps. The old app-overview.overview.apiInfo.title is only the switch's accessible label. The duplicate row under Agent Configure is merged into this one.
• Settings (Vision): app-debug.voice.settings, the key the button actually renders

Label changed to match the UI

• Explore → Web apps (explore.sidebar.webApps; en Web apps, zh WEB APPS, ja Webアプリ), plus a new Home row (common.mainNav.home). Both arrived in 1.17.0.
• My account → My Account (common.account.myAccount)
• External API → External Knowledge API (dataset.externalAPIPanelTitle)

Knowledge Retrieval node and Text Generator

• The node's labels get their own Knowledge Retrieval Node Config section. They sat under Agent Node Config before.
• The node's "Query Variable" row is replaced by Query Text and Query Images (workflow.nodes.knowledgeRetrieval.queryText / .queryAttachment).
• New rows for the metadata filtering modes Disabled, Automatic and Manual (workflow.nodes.knowledgeRetrieval.metadata.options.*.title). The ja values are 無効, 自動生成 and 手動設定.
• Query variable (app-debug.feature.dataSet.queryVariable.title, ja クエリ変数) moves to Variable Config. It renders only in Text Generator once a knowledge base is attached.

Removed

• Assistant: the existing Chatbot row covers the app type.
• No changes, and Automatic as a document processing mode (dataset-creation.stepTwo.auto): neither label exists any more. The metadata filter's Automatic is a separate label, added above.
• High-quality mode, Economy mode (Document Embedding Modes): dead keys duplicating the live High Quality and Economical rows.
• Custom moves to dataset-documents.embedding.custom.

Added

• Configure and Launch, for the Web App card's hidden-field pre-fill. The ja Launch label reads 公開.
• Knowledge Base Access, All Knowledge Bases, Specific Knowledge Bases, for the Knowledge Service API key scope.

Rule

• The UI Labels intro now says rows record the string stored at the key, even when the UI changes its case on screen (Web apps shows as WEB APPS).

Verification

• Keys and values were verified at dify 1.17.1 (8387590ace). The same keys were spot-checked on dify main, where i18n moved to web/i18n/locales/ (the key checker can't read that layout yet).
• tools/translate/check-glossary-keys.py --ref 8387590ace reports 6 dead keys out of 215, all Workspace Roles rows, which are left for the role-naming decision.
• derive-termbase.py --check is in sync.
• No docs prose uses the removed labels.

No backport: the glossary and termbase are shared writing resources. The Text Generator label fix ships separately so it can be backported on its own.
