fix: reduce aggressive orphaned position monitoring frequency

- Changed position monitor interval from 30 seconds to 5 minutes (300s)
- Reduced verbose logging in position monitor API
- Only log orphaned order checks when orders are actually found
- Prevents log flooding while maintaining functionality

- 90% reduction in monitoring frequency (30s → 300s)
- Cleaner logs with less noise
- Still catches orphaned orders effectively
- Better system performance with reduced API calls

 Verified:
- Automation page now runs monitor every 5 minutes
- Position monitor API only logs when orphaned orders exist
- System still functions correctly for cleanup
