LangSmith UI Issue: Images/Pictures no longer rendered in traces

[andrej-ilievski]

Description

After a recent UI update, images that were previously rendered inline
in traces are no longer displayed. This is a regression — the feature
was working before the update.

Steps to Reproduce

1. Create a trace that includes image inputs/outputs (e.g., base64 or
   multipart attachment)
2. Open the trace in the LangSmith UI
3. Observe that images are not rendered — only bytes are shown as text

Expected Behavior

Images should be rendered inline within the trace view, as they were
before the recent UI changes.

Actual Behavior

Images are no longer displayed/rendered in the trace UI.
