Ergonomic improvement regarding the filemanager reported by INSEE

When you upload or unzip a large file in the filemanager, the operation can take a lot of time. During this operation, the popup of the engine remains opened and the work in progress layout is active. The user has no way of knowing if everything is going well and how much more time this will take.

INSEE proposes to add a systematic message telling the user that the operation can take a lot of time

Ideally, they would like to have a progress bar showing the user the progress of the overall operation
