I'm adding TurboPower for the scroll_into_view action. It adds all the
nice CableReady actions to Turbo Streams.
Note that I omitted `block: "start"` because that option is the default
in Javascript. And the generic `action` method doesn't support
parameters like this anyway. I'll work on that in the next commit.
I also re-introduced a race condition by rendering the "loading"
indicator after triggering the report rendering job. I'm planning to
resolve that later.
