Replace fragment render functions with .sx defcomps

- Snippets list: render_snippets_list → render_to_sx("blog-snippets-content")
- Menu items list: render_menu_items_list → _render_menu_items_list helper
- Features panel: render_features_panel → render_to_sx("blog-features-panel-content")
- Markets panel: render_markets_panel → render_to_sx("blog-markets-panel-content")
