feat: #3610651 Add News demo content and category badges, fix Privacy and Programs Canvas gaps

What

• Give the News full Canvas template a title/date/Share row so Share sits inline beside the title instead of stacking below the hero image.
• Wire field_news_categories into the card-impressed overlay slot so News cards show a category badge.
• Grant "view terms in news_categories" and "view term names in news_categories" to anonymous and authenticated users so those badges are visible to all visitors.
• Add a "Stories you may also like" related-content block to the News full template.
• Add a Canvas full template for the page bundle (breadcrumb, title, field_content) so Privacy-type pages render their body instead of an empty content region.
• Give the Privacy page real body copy; it shipped with an empty field_content.
• Remove a misplaced news filter block from the Programs page; Programs has no listing view, so that block never belonged there.
• Add 15 demo News nodes (Research, Global, Students, Community) and 5 taxonomy terms backing their categories/tags, reusing existing Events/Blog media.
