fix: disable auto-translation on workflow editor to prevent React reconciliation crashes

[joelorzet]

Summary

Fixes two production errors fired 10 minutes ago on /workflows/:workflowId:

• KEEPERHUB-PRODUCTION-C — NotFoundError: removeChild ... not a child of this node
• KEEPERHUB-PRODUCTION-D — NotFoundError: insertBefore ... not a child of this node

Both stack traces are 100% inside react-dom-client.production.js (no app code). Same trace_id, same render commit, 8ms apart. Affected user: Chrome Mobile on Android 10, locale zh-CN, timezone Asia/Shanghai — classic fingerprint of Chrome's auto-translation mutating the DOM behind React's back.

Chrome/Google Translate replaces text nodes with <font> wrappers. When React later tries parent.removeChild(child) / parent.insertBefore(newNode, ref), the node isn't where React left it, so the browser throws NotFoundError. The reconciler can't recover and the editor unmounts.

Fix

Wrap the workflow editor subtree in a translate="no" div. Auto-translators skip the subtree, React's DOM assumptions hold. display: contents keeps the wrapper transparent to layout.

The marketing / hub / listing pages remain translatable, so SEO and accessibility for non-English users aren't affected.
