Pull request overview

This PR adds a new monitoring metric wal_max_count_per_table to track the maximum number of Write-Ahead Log (WAL) entries per table in the group commit feature.

• Added global metric g_wal_max_count_per_table to monitor the maximum WAL count across all tables
• Updated get_wal_queue_size() to calculate and set the new metric when querying all tables (table_id = -1)
