Now Server Reports Progress to Keep Client Connections Alive

Now server reports progress to keep client connections alive. #4215 (Ivan)
ClickHouse servers now send progress updates during query execution to keep client connections alive.

Why it matters

This feature solves the issue of client connections timing out during long-running queries by periodically reporting progress from the server, ensuring the connection remains active and responsive.

How to use it

No explicit user action is needed; the server automatically reports progress to clients during query execution to maintain connection alive status.
