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.
In the past we were using some <div> tags surrounding table action
links in order to guarantee these links wouldn't be wider that their
cell's space and wouldn't expand over two lines.
However, while these links didn't expand over two lines, at certain
resolutions the width of their text exceeded the width of the links,
causing part of the text to be outside their borders.
This behavior was also inconsistent: some tables had these <div> tags,
and some tables didn't.
Since we've now introduced the table actions component, the code is more
consistent and we're getting rid of these <div> tags. So now we're again
facing the issue where links could expand over two lines.
Using a flex layout solves this issue and considerably improves the
layout at lower resolutions.
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.
Originally, the code was shared between the index action and the search
action, but since commit fb6dbdf2 that's no longer the case. So in the
index action we don't need to check whether a user is a
moderator/manager/admin/official or not; they all are.
