refactor(popup): 5종 팝업 _i18n 주입 + 색상 토큰화 (WS-POPUP)

- 4종 팝업(command/history/result/recording-tip) _i18n 주입:
  WindowManager getPopupI18nStrings() + 팝업 script applyI18nToHtml()
- 한국어/영어 하드코딩 -> popup.* i18n 키 (ko/en 17키)
- theme-vars.ts에 --d3-wave-1~9, --d3-status-error/success 토큰 추가 (6 테마)
- 팝업 style.css hex -> CSS var 토큰
- packages/i18n getI18n() (main 프로세스용) 추가
SKIP: caption-overlay _i18n(별도 IPC 구조), wave box-shadow 보간(opacity 단순화)
