Refactored `BatchRecActionViewResponse` from a mutable class to an immutable record type with a constructor for `TotalActionCount` and a new `ActionExceptionCount` property. Moved the record to its own file under the `ReC.Application.Common.Dto` namespace.
Updated `InvokeBatchRecActionViewsCommand` and `InvokeRecActionViewsCommandHandler` to use the new record type. Removed `SuccessCount` and `FailureCount` properties, replacing them with `ActionExceptionCount`.
Performed minor cleanup, including removing the old class definition and updating namespaces.
