Increase Default replicated_deduplication_window in MergeTree Settings to 1k

Why it matters

This change expands the window in which replicated mutations and inserts are deduplicated, reducing the chance of processing duplicate data during replication and improving data consistency and correctness in replicated MergeTree tables.

How to use it

The new default applies automatically to all MergeTree tables utilizing replication. Users can manually adjust the replicated_deduplication_window setting in their table or server configuration if a different window size is desired.
