Polish Search view layout on tvOS

- Disable scroll clipping so focused source/channel/playlist cards show full halo
- Remove rounded clip on source picker row that cut the Menu focus effect
- Replace tappable recents header Button with a plain label on tvOS
- Add vertical spacing between recent search items
- Widen recent channel and playlist cards and reserve space for two-line titles
- Increase horizontal spacing between cards so focus halos don't collide
