fix: Display message content for CSAT messages in non-widget inboxes (#11528)

We made so many improvements for CSAT via https://github.com/chatwoot/chatwoot/pull/11485. However, we missed showing message content in the dashboard for CSAT URLs created in non-widget inboxes. This PR fixes the issue by ensuring that CSAT-configured messages are passed along with CSAT responses, otherwise defaulting to the translation.
