feat(activities): refine activity card for pending/rejected + compact

- Wash out pending/rejected events with opacity-50 + grayscale on a
  wrapper div so the operator sees at a glance the event isn't live,
  not just the small badge.
- Pull the status badge OUT of the wash-out wrapper and absolute-
  position it on Card root (bottom-2 left-2, z-10) so it stays in
  full color above the dim card. Both pending and rejected use the
  destructive token — the label text differentiates the two states.
  Bottom-left so it doesn't collide with the category chip on full
  cards or the thumbnail on compact ones.
- Compact rows in the Hosting view now show a small left-aligned
  thumbnail (w-20 h-20, self-center, ml-3, rounded-md) when the
  event carries an image — host can still recognize each event at a
  glance without paying the visual weight of a full hero.
- Card root becomes `relative overflow-hidden`; the wrapper div
  owns the conditional flex-row (compact) / flex-col (default)
  layout and the opacity/grayscale toggling.
