File size validation does inform the user if the file is too big

[Amantini1997]

Description

In the upload files modal, if a file exceeds the max size, we do not inform the user, who will eventually not be able to upload the files (as the button is disabled) but without knowing the reason

• This is happening in: both
• This requires a hotfix to production: no

Stakeholders

TBD

Steps to replicate

• Open the upload files modal for drawing/container
• Upload a file larger that 1GB

Current Behaviour

The file shows in the modal without any error

Expected Behaviour

I guess an alert modal should pop up informing the user about the problem and displaying the file in the modal
