Refactor SmartSource import logic to improve error handling and file …

…size checks

- Added error handling for file statistics retrieval, ensuring that errors are properly managed during import.
- Updated file size check to use a local variable for better readability.
- Enhanced import error handling to differentiate between non-existent files and other errors, allowing for appropriate actions (re-queueing or deletion).
- Improved logging for better debugging and user feedback during import operations.
