feat(dashboard): wire Anasayfa to live data

- getDashboardData aggregates open jobs, pending-action jobs, unread
  notifications, pending finance totals, approved connection count, recent
  jobs (up to 8) and recent notifications (up to 5) — single Promise.all so
  the dashboard renders in one round-trip.
- Four stat cards, each a Link to the relevant module; tone (positive /
  negative) flips between clinic (payable) and lab (receivable).
- Clinic users with zero approved connections see a 'Bağlantı Kur' prompt
  card so they don't get stuck on /jobs/new.
- Recent jobs table is role-aware: lab sees Klinik column + 'Son Gelen
  İşler' header, clinic sees Laboratuvar column + 'Son Giden İşler' header.
- Recent notifications panel with read/unread dot, clickable header arrow
  to /notifications.
- ActiveContext now carries 'kind' (mirror of TenantSettings.kind) so we no
  longer reach into ctx.settings?.kind in callers.
