feat: news story cards in briefing — backend embeds structured RSS items in metadata

Previously metadata only stored rss_item_ids (integers); the full item data
was discarded after LLM synthesis. Now rss_items (id, title, url, source,
snippet, published_at) is also stored so clients can render per-story cards
without additional API calls.

Web BriefingView: replaces bare reaction-row buttons with news cards showing
source, headline (linked), 2-line snippet, and 👍/👎 per card.
