fix(web): add missing market.componentName i18n keys

The marketplace component filter (and component badges) used
market.componentName.{Tool,Command,EventListener,KnowledgeEngine,Parser,Page}
but those keys only existed under plugins.componentName, so the market UI
showed raw keys. Add a componentName block to the market namespace (zh-Hans +
en-US; other locales fall back to zh-Hans).
