Implement Chunks Page and Update SearchPage Component

- Introduced a new ChunksPage component to display chunks of a selected file, enhancing the knowledge management functionality.
- Updated the SearchPage component to navigate to the ChunksPage when a file is selected, improving user flow.
- Removed the previous file selection logic and integrated a more streamlined approach for chunk display.
- Enhanced UI elements for better user experience and accessibility.
