We had inconsistent indentation in many places. Now we're fixing them
and adding a linter to our CI so we don't accidentally introduce
inconsistent indentations again.
Using the standard `confirm` parameter, we can remove all the custom
code we added to do the same thing.
Since the code is similar, we're doing the same when asking for
confirmation to send notifications.
This way it will be easier to change the behavior of all table actions,
like adding ARIA attributes. In the past, when we changed the behavior
of the `link_to` method, we had to change all table action classes.
Note the CSS could probably be improved to avoid duplication with other
button style definitions. However, that's fine because we're going to
change the style of the links soon.
For the same reason, I haven't bothered to style every single link the
way it was until now.
This partial was going to get too complex since in some places we've got
different texts, different URLs or different confirmation messages.
While we should probably try to be more consistent and that would make
the partial work in most cases, there'll always be some exceptions, and
using a partial (with, perhaps, some helper methods) will become messy
really quickly.
The same way we did for banners.
We needed to add new translation keys so the labels are displayed in the
correct language. I've kept the original `title` and `body` attributes
so they can be used in other places.
While backporting, we also added the original translations because they
hadn't been backported yet.
In Madrid, the button text didn't change depending on whether the form
is for the "new" page or for the "edit" page.
In consul, the buttons texts were "create admin notification" and
"update admin notification" instead of "create notification" and "update
notification".
Also change translation key from "submit" to "submit_button" to
match other instances.
In the same fashion Newsletters is managed, with the only difference that
the preview is using the notification partial in the same way the index
of notifications.
