* [fix](image) fix bug that latestValidatedImageSeq may not be the second largest image id When traversing the image files in the meta directory, it cannot be guaranteed to be traversed in the order of imageid size For example, if it traverses the image file with orders like: 3,5,4,1, then latestImageSeq is 5, but latestValidatedImageSeq is 3, which is wrong.
