Centralized Wallet Service Integration

• Row-Level Locking: Concurrent wallet updates properly synchronized
• Safe Arithmetic: Precision-safe calculations eliminate floating-point errors

Notification Service Migration

Futures trading notifications now use the new multi-channel notification service:

• Multi-Channel Support: Notifications sent by in-app message, email, SMS and push
• Position Notifications: Real-time alerts for position updates and liquidations
• Idempotency: Prevents duplicate notifications from retried operations
• User Preferences: Respects per-user notification channel preferences

Trading Operations

• Changed exchange order wallet operations to run through the centralized service.
• Changed position opening and closing to use atomic operations.
