Fix: Position Manager initialization race condition in API endpoints

- Changed /api/trading/positions to use getInitializedPositionManager()
- Changed /api/trading/test to use getInitializedPositionManager()
- Changed /api/trading/test-db to use getInitializedPositionManager()
- These endpoints were accessing Position Manager before DB restore completed
- Now properly wait for async initialization before accessing trade data
- Fixes /status Telegram command showing empty despite active positions
