feat: news story cards in Android briefing screen

Replaces bare Story-N reaction rows with full NewsCard widgets: source label,
relative timestamp, linked headline, 2-line snippet, and 👍/👎 reactions.
Reads rss_items from message metadata (requires backend ≥ this sprint).

Adds url_launcher ^6.3.1 for opening article links in the browser.
Adds https/http <queries> entries to AndroidManifest for Android 11+.
