Description

Currently, the Optimizing tab in the Tables detail page displays all process types together, including both optimization processes (MAJOR/MINOR/FULL) and maintenance processes (EXPIRE_SNAPSHOTS, CLEAN_ORPHAN_FILES, etc.). This creates confusion for users who need to quickly find specific types of processes.

This subtask introduces a new Maintenance tab in the Tables detail page to provide clear separation between optimization and maintenance processes.
