Refactored ActionService to use constructor injection for IRepository<History>. Updated all public methods to accept optional CancellationToken parameters for improved cancellation support. Added necessary using directives. Class remains a placeholder with [Obsolete] attributes and NotImplementedException.
Added an XML summary comment to the ActionService class to indicate it is being migrated from EnvelopeGenerator.CommonServices.Services.ActionService. This provides clarity on the class's origin and intended purpose; no functional changes were made.
ActionService is now marked obsolete as a placeholder. Its constructor was removed, and all methods now throw NotImplementedException instead of returning true. Each method is also marked obsolete, indicating logic should be migrated from CommonServices.Jobs.
