feat(malaysia): 전 화면 한글/영문 실시간 토글

- static/malaysia.js: KO_EN 사전 + 토글(localStorage 기억, 새로고침 없이 즉시)
- _i18n.html 공용 include(ENG/한글 버튼 + 스크립트), 전 화면 상단 삽입
- UI 고정 문구는 사전 치환(제목/헤더/버튼/라벨/배지/옵션/안내)
- 상품/콤보명은 data-en(영문, malaysia_items)·data-ko(itemcode_db 한글) 동시 렌더
- _base_ctx 에 ko_names(itemcode_db name_map) 주입
