Add Random Sleep to Balance Load During Merges in Zero-Copy Replication

Add random sleep before large merges/mutations execution to split load more evenly between replicas in case of zero-copy replication. #51282 (alesapin).
Adds a random sleep delay before executing large merges and mutations to better distribute load between replicas during zero-copy replication.

Why it matters

To prevent load spikes by staggering merge and mutation execution times on replicas, which helps in evenly distributing resource usage and improving cluster stability and performance.

How to use it

This feature is applied automatically to large merges and mutations when zero-copy replication is enabled; no additional configuration is required from the user.
