Restore Live shelf on Today, flatten Feed to time-ordered highlights

Today tab: Removed LiveSituationBar, restored the full Live game shelf
below the featured Astros card where it belongs.

Feed tab: Changed from two grouped shelves (condensed / highlights) to a
single horizontal scroll with ALL highlights ordered by timestamp (most
recent first). Added condensed game badge overlay on thumbnails. Added
date field to Highlight model for time-based ordering.
