Change Warning for High Number of Attached Tables to Differentiate Tables, Views, and Dictionaries

Change warning on high number of attached tables to differentiate tables, views and dictionaries. #64180 (Francisco J. Jurado Moreno).
Improved warning messages for high numbers of attached tables by distinguishing between tables, views, and dictionaries.

Why it matters

To provide clearer diagnostics when many tables are attached in ClickHouse by differentiating the count of regular tables, views, and dictionaries, helping users better understand their database structure and optimize resource usage.

How to use it

No special action required. When the number of attached tables exceeds a threshold, ClickHouse now issues more informative warnings specifying counts for tables, views, and dictionaries separately.
