Wire up real implementations for Tracking & Config controllers

- TrackingController: Added database persistence for analytics events
  * Created AnalyticsEvent entity with user/session tracking
  * Store event type, data (JSON), and timestamp
  * Graceful fallback if DB write fails (game doesn't break)

- ConfigController: Added real player counting
  * Query active sessions from last 15 minutes
  * Return actual player count instead of hardcoded 0
  * Real-time server status with DB metrics

- Added AnalyticsEvents table migration
  * Stores all game telemetry for analytics
  * Indexed by UserId for performance
  * JSON event data for flexibility

Controllers now fully wired to database:
- 11/18 controllers REAL implementation ✅
- 5/18 controllers STUB (config-based) ⚠️
- 2/18 controllers SERVICE (delegated) ⚠️

Total: 95 endpoints, improving from demo to production
