Maxiwere45 a2a7ffd79f feat(i18n): add FR/EN internationalization with in-app language selector
- gen-l10n setup (flutter_localizations, intl, l10n.yaml, ARB en/fr)
- localeProvider (persisted) wired into MaterialApp
- language selector in the System page (alongside the color palette)
- all user-facing strings across screens moved to AppLocalizations
