fix(domains): backend column showed (undefined:undefined) instead of scheme

BackendLite interfaces in Domains list and Detail declared address/port
fields that don't exist on the Backend model (those live on BackendServer).
Every backend tag rendered as "name (undefined:undefined)". Fixed by
replacing the phantom fields with scheme, so tags show e.g. "my-app (https)".
