  subHideSettings (bool) in AllSetting and AllSettingView
- Add subHideSettings / subHideSettingsDesc translation keys to all 11
  remaining locales: ar-EG, fa-IR, es-ES, id-ID, ja-JP, pt-BR, uk-UA,
  tr-TR, zh-TW, zh-CN, vi-VN

* fix(sub): add subHideSettings default to settings map

Every other sub* setting has an entry in defaultValueMap; subHideSettings was missing, so GetSubHideSettings hit the 'key not in defaultValueMap' error path on a fresh install (only masked by the false fallback in sub.go). Add the default for consistency.
