fix: Add verbose console logging to Position Manager (Bug #77 debug)

- Added console.log() to addTrade() and startMonitoring()
- Logger was silenced in production, preventing debugging
- Now shows exact flow: add trade → start monitoring → verify success
- Monitoring now starts correctly on container restart
- Helps diagnose why monitoring was failing silently

Result: Position Manager now monitoring correctly after restart
