refactor(kegiatan-desa): redesign public list page to card grid + kategori filter

- Remove hero/featured section and tab navigation
- Redesign to pecalang-style: 3-col card grid (image, title, desc, Detail button)
- Replace tabs with Select dropdown filter by kategori
- Search + kategori filter use query params, stay on /semua route
- Image hidden when empty (no placeholder)
