banners: Hide empty banner-action-buttons using CSS.

Browse Source 
Previously, the action buttons container was only hidden via
conditional rendering in the template. This commit adds a CSS-based
approach to also hide the container when it becomes empty, using the
:empty pseudo-class. This ensures correct behavior if we later have a
class of banners where the buttons area is dynamically updated, and
buttons are removed dynamically.
