use correct cloud agent icons for 3p conversation transcripts (#10148)

## Description
<!-- Please remember to add your design buddy onto the PR for review, if
it contains any UI changes! -->

We weren't properly checking/respecting 3p agent harness information for
cloud conversation transcripts when deciding which icon to display in
the conversation list, vertical tabs, and pane header.

## Screenshots / Videos
<!-- Attach screenshots or a short video demonstrating the change, where
appropriate. Remove this section if it is not relevant to your PR. -->
