Added Query-id to Server's HTTP Response Header

Added Query-Id to Server's HTTP Response header. #4231 (Mikhail)
Added the Query-Id header to the HTTP response from the ClickHouse server.

Why it matters

This feature allows users to easily track and identify queries by including the Query-Id in the HTTP response headers. It improves query monitoring and debugging in HTTP client interactions.

How to use it

When sending queries over HTTP to ClickHouse, the server response will include a Query-Id header automatically. Users can read this header to obtain the unique identifier of the executed query.
