refactor(GUI): reuse WarningModalService in FlashErrorModal (#1051)

This is the first commit in a series of changes to normalise the use of
modals throughout the application.

`FlashStateModel` is basically a `WarningModalService` that cleans the
flash state, therefore making it re-use `WarningModalService` directly
removes unnecessary duplication.
