* Implement cleanupCipher method in BaseImporter with tests for notes and name handling
- Added cleanupCipher method to preserve leading/trailing spaces in notes and set them to null if they contain only whitespace or are empty.
- Updated the BaseImporter class to remove trimming of notes to maintain original formatting.
- Added unit tests for cleanupCipher to verify behavior for various note and name scenarios.
