Replace Feed with highlights, remove duplicate live shelf, drop Intel schedule

Feed tab: Replaced news/transaction feed with league-wide highlights and
condensed game replays. FeedViewModel now fetches highlights from all
games concurrently, splits into condensed games vs individual highlights.
Cards show team color thumbnails with play button overlay.

Today tab: Removed duplicate Live games shelf — LiveSituationBar already
shows all live games at the top, so the shelf was redundant.

Intel tab: Removed schedule section (already on Today tab). Updated
header description and stat pills. Added division hydration to standings
API call so division names display correctly instead of "Division".

Focus: Added .platformFocusable() to standings cards and leaderboard
cards so tvOS remote can scroll horizontally through them.
