feat: Replace placeholder data with database queries in charging service methods
- Update GetSystemStats to query active sessions, total accounts, blocked users, and low balance alerts from database - Update GetHealthStatus to check database connectivity and set ActiveSync status - Update GetUsageStats to query usage events by IMSI and period with trend calculation comparing to previous period - Update GetRealTimeUsage to query current session and today's usage from database - Update ListUsageEvents to query usage events with
