✨ feat(stats): add user statistics to Prometheus metrics and Grafana

Browse source 
- Add user metrics to mana-core-auth MetricsService:
  - auth_users_total: Total registered users
  - auth_users_verified: Email-verified users
  - auth_users_created_today/this_week/this_month
- Create Grafana user-statistics dashboard with:
  - User overview stats (total, verified, verification rate, new today)
  - Registration period breakdown (today/week/month)
  - User growth trends over time
- Enhance telegram-stats-bot /users command:
  - Add yesterday comparison with trends
  - Add week-over-week comparison
  - Add mini bar chart for last 7 days registration
- Include user stats in daily Telegram report
