WPB-21656 [iOS] Sorting in all files

Issue

This PR replaces the attachment Menu that shows up when a file could not be uploaded as it was introducing a UI bug when the keyboard was showing. As discussed with design team, we prefer to display an alert instead to avoid that bug.

Testing

have an attachment uploaded that ends up in error, tap on the "elipsis" button in top right corner of the attachment. Before it was showing a context menu, now it displays an alert, same actions as before (remove file or retry).

A little bit sad as alerts are quite aggressive but I guess at least it provides space to give reason for the error in the future.
