Allow directory upload and Sort all files

[RainBoltz]

What is the problem?

1. we cannot upload the whole directory, so it will take a long time to upload files if there are a lot of files
2. the website cannot handle the files that are in different directories but with the same name
3. vulnerability issue

Fixed

1. support directory uploads with specified file extensions
2. auto sort files to make it better to filter out the files we don't need
3. fix all vulnerabilities (Node.js 22)
