Renamed all `Guid` properties and parameters to `Id` in update procedure interfaces, records, and handlers. This clarifies that the identifier is a numeric ID, not a GUID, and improves consistency across the codebase. All related method signatures and usages have been updated accordingly.
Introduced a new namespace `ReC.Application.Common.Procedures.UpdateProcedure` and added the `IUpdateProcedure` interface. This interface defines a `ToObjectProcedure` method for converting to an `UpdateObjectProcedure`. The method accepts a `guid` parameter and an optional `changedWho` parameter to track changes. This addition establishes a contract for handling update procedures.
