Add debug logging for Docker container and image collection

Agent changes:
- Added debug logging to Docker images collection function
- Log when Docker sub-services are being collected for a service
- Log count of containers and images found
- Log total sub-services added
- Show command failure details instead of silently returning empty vec

This will help diagnose why Docker images aren't showing up as sub-services
on some hosts. The logs will show if the docker commands are failing or if
the collection is working but data isn't being transmitted properly.

Updated to version 0.1.175
