The `use_helpers` method was added in ViewComponent 3.8.0, and it's
included by default in all components since version 3.11.0.
Note we sometimes delegated the `can?` method to the controller instead
of the helpers, for no particularly reason. We're unifying that code as
well.
We currently don't have any links in the public area pointing to past
budgets, so having links in the admin section to both the budget and its
results seemed a bit redundant. We're going to add more links to the
budget actions soon, so we need to make room for them; otherwise we'll
have too many.
We're also changing the "Preview" text for a published budget. Since the
budget is already public, we aren't previewing it anymore but simply
viewing it.
And, to be consistent with the "See results" link, we're opening the
"Preview" link in the current tab. Opening links in a new tab is
generally a bad idea because takes control away from users, breaks the
back button and makes navigation particularly hard on mobile browsers.
It could be argued that in this case it's useful when users are editing
the budget in one tab and previewing it in another one, so we might add
this behavior back as long as we make it clear that the link opens in a
new tab [1].

Having links in the middle of a form distracts users from the task of
filling in the form, and following a link before submitting the form
will mean whatever has been filled in is lost.
And the budgets form is already very long and hard to fill in. Having
the phases table in the middle of it made it even harder. And, since
we're planning to add the option to manage groups and headings from the
same page, it's better to have a dedicated page for the form.
