fix(control-units): list zimage controlnets under 'all'; fix LLLite output-block fall-through

api_list_models omitted the 'or model_type == all' clause for zimage, so ZImage ControlNets never appeared in the all listing - added it to match every other family. lite_model used pass for the unimplemented root==output branch, which fell through to b = getattr(b, attn_name) with b unbound or stale from a prior iteration (UnboundLocalError or wrong-block patch); use continue to skip it.
