feat: add File Upload node functionality and related components

- Implemented File Upload node with support for uploading files to the sandbox.
- Added necessary UI components including node panel and default configurations.
- Enhanced workflow constants and enums to include File Upload.
- Updated error handling for file upload operations.
- Integrated File Upload into existing workflow structure, ensuring compatibility with variable handling and output management.
- Added translations for new File Upload features in workflow.json.
