The translation key structure was changed from language to languagePicker, but the old language.changeLanguage key is still referenced in packages/web/src/components/DeviceInfoPanel.tsx at line 138. This change will cause a missing translation for that component.

Additionally, all other locale files (de-DE, es-ES, fr-FR, etc.) still have the old language key structure and do not have the new languagePicker key. This means the language switcher will not be properly translated for non-English users.
