fix(frontend): align catalog with dashboard, make disease cards clickable, fix stat cards

- Make dashboard disease quick-access cards clickable → link to /catalog/:slug
- Update catalog page to match dashboard styling (4-column grid, consistent
  card design with colored dot, risk badge, line-clamp summary)
- Add URL param support to catalog (?risk=high) so dashboard's
  "Risiko Tinggi" stat card link works
- Remove confusing "Total Penyakit" stat card (was counting catalog rows,
  always 4). Replace with "Total Diagnosa" linking to /diagnoses,
  "Gagal" stat, and rename "Risiko Tinggi" to "Kategori Risiko Tinggi"
  linking to /catalog?risk=high
