[Feature]: Implement Route-Based Code Splitting to Improve Initial Load Performance #68

Description of the Feature
Currently, the React application loads the entire JavaScript bundle for all routes (including Dashboard, Profile, About, and Contact) during the initial page load. This results in a larger-than-necessary bundle size, slowing down the first contentful paint and Time to Interactive (TTI), especially for users on slower networks or mobile devices.
This feature proposes to implement route-based code splitting using React.lazy() and Suspense. This will break the main bundle into smaller chunks that are loaded only when the user navigates to a specific route. This is a React-recommended best practice for performance optimization.
Key Changes:
Convert static imports for route components to dynamic imports using React.lazy.
Wrap lazily-loaded components in a Suspense component to display a fallback UI (e.g., a loading spinner) while the chunk is being fetched.
This change will be seamless to the user but will significantly improve perceived performance.
Estimated time to implement the feature
2-3 Days (This includes testing the lazy loading and creating a simple fallback component)
Benefits:
Reduced initial bundle size.
Faster initial page load time.
Improved performance scores (Lighthouse, PageSpeed Insights).
Better user experience, especially on low-end devices.
