[CCR][FE Binlog] Temporary-table CREATE is filtered but DROP_TABLE still enters the database Binlog

## Problem

[CCR][FE Binlog] Temporary-table CREATE is filtered but DROP_TABLE still enters the database Binlog

## Minimal reproduction path

Enable database-level CCR metadata Binlog, create a temporary OLAP table, and immediately drop it. Inspect the database Binlog and dropped-table records. Verify that the temporary table produces neither CREATE_TABLE nor DROP_TABLE metadata events, while an ordinary table still produces the expected drop event.

## Expected result

Temporary-table CREATE and DROP are consistently excluded from database metadata Binlog.

## Source

This report is a sanitized tracking record for Jira DORIS-28092. Internal hosts, paths, artifacts, build identifiers, and private logs are intentionally omitted.

Start by enabling database-level CCR metadata Binlog and reproducing the temporary-table CREATE and DROP sequence described in the issue. Inspect the resulting database Binlog and dropped-table records; done means temporary tables produce neither CREATE_TABLE nor DROP_TABLE events while ordinary tables still produce the expected drop event.
