fix: improve file name generation in upload_file function to prevent files with the same name

[anovazzi1]

The file name generation in the upload_file function has been improved to prevent files with the same name. Previously, the function used the received file name, but now it also includes the file extension. This ensures that each file has a unique name.
fix #3400
