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.
