feat(exclusions): Integrate exclusion UI in CtaBoxSidebar component

- Add ExclusionFormPartial to CtaBoxSidebarFormBuilder
- Add _exclusions fields to CtaBoxSidebarFieldMapper with types
- Update AdminAjaxHandler to process json_array types via ExclusionFieldProcessor
- Enqueue exclusion-toggle.js in AdminAssetEnqueuer

The exclusion UI now appears in CTA Box Sidebar visibility section,
allowing admins to exclude component from specific categories,
post IDs, or URL patterns.
