[Dashboard][Info] TerminalPassthrough silently swallows message fetch errors

[OneStepAt4time]

Summary

TerminalPassthrough.tsx:82-98 — If getSessionMessages fails (network error), the error is silently swallowed — the .then() chain has no .catch(). loadingMessages is set to false, but the user sees no error indication and the transcript appears empty.

Files Affected

• dashboard/src/components/session/TerminalPassthrough.tsx:82-98

Suggested Fix

Add a .catch() handler that sets an error state, similar to how TranscriptViewer handles it (line 58-59).

🔧 Starting work. Approach: add proper error handling for message fetch failures in TerminalPassthrough component — surface errors to UI instead of silently swallowing.
