Enhance FileOperationModal and introduce FileStack component

- Updated FileOperationModal to fetch and display file information for both source and destination, improving user experience.
- Added FileStack component to visually represent multiple files stacked with rotation, enhancing the file selection interface.
- Refactored source and destination file displays to conditionally render file thumbnails or icons based on availability.
- Improved layout and styling for better clarity and consistency in file operations.
