Fix folder display and add validation to file listing operations

- Handle folder names properly in getDisplayName by preserving trailing slash
- Add validation to skip invalid objects during listing
- Add default values for missing object properties (size, lastModified, etag)
- Add debug logging for listObjectsV2 operations to help troubleshoot issues
- Add null checks in deleteFolder to prevent errors with invalid objects
