Like a5f3318f3b, this proves that the new dispatcher conversion works for fire-and-forget style dispatches too. This is another obvious-if-broken and generally safe conversion to make.
Other actions which can be dispatched this way have been excluded for reasons mentioned in the Action enum's comments.
This is a relatively obvious dispatch action that doesn't require a lot of complicated type definitions, so should be a good candidate to prove the thing works. If for some reason the thing stops working, we've done something wrong.
This also adds a bit of generic types to the dispatch call so we don't confuse the tsx parser by using `dis.dispatch(<ViewUserPayload>{...})` as it thinks that's supposed to be a component. We still get type safety, and the thing remains happy with the generics approach.
