[Binlog] BE restart recovery can mismatch companion rowsets across multiple tablets sharing a transaction #67091

Problem

[Binlog] BE restart recovery can mismatch companion rowsets across multiple tablets sharing a transaction

Minimal reproduction path

Create a local ROW Binlog table with at least two buckets placed on the same backend and data directory. Make one transaction write both tablet pairs, pause publication after commit, restart the backend, resume publication, and compare each base tablet with its companion row-binlog tablet. Verify that every pair keeps its own transaction, tablet identity, version, and events, with no orphan committed companion.

Expected result

After backend restart and publication, every base/companion pair remains one-to-one and all row-binlog events are preserved.
