Add comprehensive platform administration panel

- Database: Add login_history, ai_recommendation_log tables; is_platform_owner
  column on users; subscription fields on organizations (payment_date,
  confirmation_number, renewal_date)
- Backend: New AdminAnalyticsService with platform metrics, tenant detail, and
  health score calculations (0-100 based on activity, budget, transactions,
  members, AI usage)
- Backend: Login/org-switch now records to login_history; AI recommendations
  logged to ai_recommendation_log; platform owner protected from superadmin toggle
- Frontend: 4-tab admin panel (Dashboard, Organizations, Users, Tenant Health)
  with tenant detail drawer, subscription management, health scoring visualization
- Platform owner account (admin@hoaledgeriq.com) auto-redirects to admin panel
- Seed data includes platform owner account and sample login history
