Subject: [PATCH] feat(12-01): update i18n store lang init to use
 navigator.language fallback

- Replace hardcoded 'fr' default with IIFE that checks localStorage first
- Falls back to navigator.language: 'en' if starts with 'en', else 'fr'
- localStorage preference always wins over browser language setting
