Removed Redundant Checksum Checks for Data Parts

Removed redundant checking of checksums when adding a data part. This is important when there are a large number of replicas, because in these cases the total number of checks was equal to N^2.
Removed redundant checksum verification when adding data parts to optimize performance in environments with many replicas.

Why it matters

The feature eliminates unnecessary duplicate checksum checks during data part addition, which previously caused the total number of validations to scale quadratically (N²) with the number of replicas. This significantly improves efficiency and reduces overhead in clusters with a large number of replicas.

How to use it

This optimization is applied automatically in the data part addition process and requires no additional configuration or action from users.
