Show sponsor badge next to names everywhere + update app icon

- Sponsor heart now appears in the chats list (DialogCell), chat header
  (ChatAvatarContainer), message author names (ChatMessageCell) and user
  lists (UserCell), not just on the profile screen
- Added ShimmerHeartDrawable.drawStatic() for cheap static rendering in
  frequently-repainted list cells; header keeps the animated shimmer
- Cells request sponsor status via SponsorHelper batch lookup and redraw
  on sponsorStatusUpdated
- Regenerate launcher icon from updated foxigram4.png
