Description
## Problem
[CCR][FE Binlog] Binlog configuration events diverge between leader and follower
## Minimal reproduction path
Run a frontend cluster with CCR metadata Binlog enabled. Change Binlog configuration once with a warm cache and once with a cold cache, replay the same journal on a fresh frontend, and compare events by logical object and operation. Verify that leader, follower, and restart produce the same configuration event set.
## Expected result
The same configuration journal produces the same Binlog events on leader, follower, and restart.

Contributor guide
Research direction
Start by reproducing the warm-cache and cold-cache Binlog configuration changes in a frontend cluster with CCR metadata Binlog enabled, then replay the journal on a fresh frontend. Compare leader, follower, and restart event sets by logical object and operation; done means the same journal yields identical configuration events.】【。
