feat(web): add i18n support with FR/EN locales and keyboard layout awareness

Add full internationalization system with React context, French/English
translations, and AZERTY/QWERTY keyboard layout support. Dashboard now
uses a tabbed layout (Tools, Notifications, Workflows). Config page exposes
language and keyboard preferences persisted via new /api/preferences endpoint.
