Subject: [PATCH] refactor(history): introduce extension method and remove
 AutoMapper dependency

- Added `CountHistoryQueryExtensions.AnyHistoryAsync` for cleaner query usage via `ISender`.
- Removed `IMapper` from `CountHistoryQueryHandler` as it was unused.
- Removed unnecessary `using` directives to simplify imports.
- Kept query handling logic intact.
