Builder compatibility and editing improvements
This release improves Ghost Source compatibility, reduces styling conflicts, and makes block editing more reliable in the visual builder.
Added smooth scroll support and common Source theme classes for better compatibility with Source-based custom styles.
Added bordered button color selection for more flexible CTA styling in sections that use bordered button variants.
Improved nested block editing by supporting context menus consistently in both the preview canvas and sidebar.
Switched navigation rendering to the standard Ghost {{navigation}} partial for closer Source theme behavior.
Fixed block field naming and button config migration paths to avoid Ghost rendering conflicts and preserve legacy button content.
Fixed style conflicts by removing the social links .nav class and correcting bordered color mapping in card-icon and eyebrow blocks.
