Subject: [PATCH] Limit blog filter categories control to portfolio by default

Reintroduce a Portfolio-only default for the filter categories checkbox and expose a new siteorigin_widgets_blog_filter_categories_templates hook so extensions can opt-in additional templates. Reuse the filtered template list for both the settings and design state handlers to keep the UI consistent.
