### What problem does this PR solve? Streaming CDC jobs periodically fetch the source end offset, while a successful task commits its current offset independently. A task can advance beyond the previously fetched end offset. The FE previously converted the offset comparison into a boolean, so it could stop scheduling but could not distinguish equality from the current offset being ahead, leaving CurrentOffset greater than EndOffset in job output. This change preserves the three-way comparison result and advances EndOffset to CurrentOffset when the fetched end is behind. End-offset publication is synchronized so an obsolete comparison result cannot overwrite a newer fetched end. The PostgreSQL latest-offset credential regression case now waits for the first task to commit the resolved latest offset before inserting new rows.
