Final issues before delivery

[ElevnLi]

1. cvat uploader cannot transfer back the category name to the front button after clicking the apply button
2. apply the spinner to the next button of cvat uploader, maybe tweak the logic a bit to make it smoother
3. weedcoco upload seems not showing missing images after uploading the weedcoco file
4. uploading individual large image seems not working, only zip file uploader is working now
5. maybe put down some points of what to test and how to test the whole workflow of uploading, editing and removing the dataset in all different format and data size
