Unify budget landing pages

There was a big difference between the current budget and a specific
budget landing page. This didn't really make too much sense. Also, it
was not possible to know how a draft participatory budget will look
before it was published.

By unifying those two views now they will look quite similar and it
will be possible for administrators to preview any draft budget and to
know how the budget will look like before actually publishing it.
