If we don't explicitly handle random unexpected exceptions, the error
that the front end receives includes a big ole stacktrace, which is
unhelpful for regular users and possibly bad to expose. Instead, we
should provide a vague "something went wrong" message.
Separately, we can create a default SnackBar options and use that (we
want it longer than 1.5 seconds because that's pretty short).
This isn't the prettiest thing, but it replicates the type of view /
edit functionality that we had in the original console.
Of note: this doesn't include input field validation, which would
probably be a good idea to add at some point.
