feat: 템플릿 기반 어댑터 에러 메시지 핸들러 추가

AdapterPropManager "AdapterErrorMessageHandler" 그룹의 {adapterGroupId}.template 키로 등록된 템플릿을 읽어 StandardMessage 및 callProp 값으로 치환한 에러 응답을 생성한다. 변수 치환 규칙: - ${callprop.키} → callProp.getProperty("키") - ${MSG.MAIN_MSG.경로} → StandardMessage.findItemValue("경로") - {{#foreach 경로}}...{{/foreach}} → GRID 배열 반복 (쉼표 구분) JSON/XML 템플릿 모두 지원 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
