Move EndpointAuth procedures to dedicated namespace

Refactored Delete/Insert/UpdateEndpointAuthProcedure records into the new ReC.Application.EndpointAuth.Commands namespace for better organization. Updated using statements in related files to ensure compatibility. No functional changes to the procedure records themselves.
