[TASK] Always show action icons in tables (em, docs)

The goal to hide actions icons has not been reached. Since the
hiding the icons is worse than showing all icons we revert to
the prior behaviour.

In the long run secondary and extended options / actions will
have to move into the Clickmenu. Show only primary actions.
