💡 What: Optimized `LanguageProvider` to use lazy state initialization for `language` and removed `isInitialized` state.
🎯 Why: The previous implementation triggered a second render on mount because it initialized state to 'de' and then updated it in a `useEffect`.
📊 Impact: Reduces initial render count of the entire application by 50% (from 2 to 1).
🔬 Measurement: Verified with `src/i18n/__tests__/initialRender.test.tsx` which confirms the render count is now 1.
