Updating modification_time for system.parts after part movement

Why it matters

This feature ensures that the modification_time reflects the latest changes when a data part is moved, providing more accurate and reliable metadata about part modifications. This helps users and administrators track the most recent changes to parts, especially during operations like replication or data rebalancing.

How to use it

The feature is applied automatically when data parts are moved. Users do not need to enable anything explicitly; the modification_time column in the system.parts table will now be updated accordingly.
