• Accept an array for `actionsArea`, enabling multiple action blocks in one card
• Automatically insert a `Divider` between consecutive action blocks
• Add a `Divider` between `actionsArea` and `searchArea` when both exist
• Standardize `Divider` spacing by removing custom `margin` props
• Update `PropTypes`: `actionsArea` now supports `arrayOf(node)`

These changes improve visual separation and usability for complex table cards (e.g., Channels), making the UI cleaner and more consistent.
