Key Changes:
- Created Wrapper components (Fullscreen, Column, Container, ListedComponent) to standardize the application's overall layout.
- Refactored the structure of major components like App.tsx and PageContainer.tsx to use the new Wrapper components.
- Added a simple TodoBoard mockup page at the /todos route.
- Adjusted flexbox classes for the TodoBoard component to allow its width to resize flexibly based on screen size.
