[codex] fix: guard trace ID clipboard copy

[StiensWout]

Summary

• Route the saved backend row trace ID copy action through the existing guarded clipboard hook.
• Show success feedback when the trace ID is copied.
• Show the hook-provided clipboard error message when the Clipboard API is unavailable or write fails.

Root cause

The saved backend row called navigator.clipboard.writeText(errorTraceId) directly, so unsupported clipboard contexts or rejected writes could fail without the existing user-visible error handling.

Impact

Users keep the same Copy trace ID action, but failures now surface as an error toast and successful copies confirm the copied trace ID.

Validation

• PATH="$HOME/.vite-plus/bin:$PATH" vp check
• PATH="$HOME/.vite-plus/bin:$PATH" vp run typecheck

vp check reports the repository existing unrelated warnings and no errors.

Note

Low Risk
Single UI handler change in Connections settings with no auth, data, or API impact.

Overview
Copy trace ID on saved remote backend rows (when a connection error includes a trace ID) no longer calls navigator.clipboard.writeText directly.

It now goes through useCopyToClipboard with target: "trace ID", matching pairing-link copy behavior: a success toast shows the copied ID, and unavailable or failed clipboard writes surface an error toast via stackedThreadToast.

Note

Guard trace ID clipboard copy in SavedBackendListRow with success and error toasts

Replaces the direct navigator.clipboard.writeText call with a useCopyToClipboard helper in ConnectionsSettings.tsx. On success, a 'Trace ID copied' toast displays the copied ID; on failure, an error toast is shown via stackedThreadToast instead of silently failing.

Approvability

Verdict: Approved

Small UX improvement that adds toast notifications when copying trace IDs to clipboard, replacing a raw clipboard API call with the existing useCopyToClipboard hook pattern. Self-contained change with no significant runtime behavior impact.
