Fix post height in Posts block

Styling bug in the Kadence Posts block: When Kadence switched to using lists to display posts, the theme was updated to display posts with a uniform height on a boxed layout. However, it looks like the Kadence Blocks Posts block was not. As a result, entries listed in a boxed layout using the Posts block have uneven heights.

The following is a quick fix:

.wp-block-kadence-posts .entry {
    height: 100%;
}

However, it would be better to update the block to align with the styling used in the theme’s default posts layout for consistency.
