This also resolves a race condition scenario. Even if the report gets
rendered via websockets before the controller response is rendered then
the fallback script loads the report again. It's not the most beautiful
but probably okay until we replace websockts altogether.
I'm leaving websockets in at the moment because it can render the report
much quicker than polling can.
The helpers are more convenient but also allow us to add options like
smooth scrolling. I thought that looked nicer and is less confusing.
Please note that the `scroll_into_view` helper uses the `targets`
attribute instead of `target`. That attribute needs CSS selectors with a
leading `#` for ids.
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.
