   웹메일 언어 전환 UI (webmail-i18n.js 가 동적으로 마운트)

   두 가지 변형:
     - .webmail-i18n-switcher-inline   : 공통 헤더(.mail-header .header-actions) 안.
                                         헤더가 어두운 배경이라 흰색 계열로 맞춘다.
     - .webmail-i18n-switcher-floating : 헤더가 없는 화면(로그인/비밀번호 변경)에서
                                         우측 상단 고정. 밝은 배경 기준.
