attach error snackbar in modals
In the absence of correct detection by Nuxt (a package update could be a solution that we will explore in another MR), we have set up a snackbar in the event of an error in 2 situations. The snackbar was displayed at the bottom of the page and not in the modal where the error occurred. The purpose of this MR is to put it in the modal.
