Add EndpointAuthId to support endpoint authentication

Introduced a new `EndpointAuthId` property in `RecActionController` and `CreateRecActionCommand` to enable handling of endpoint authentication. Updated the `RecActionController` to initialize `EndpointAuthId` with a default value of `1`. Modified the `CreateRecActionCommand` record to include a nullable `EndpointAuthId` property of type `long?`, allowing optional specification of authentication details.
