- routes/host_compliance_discovery.py -> routes/hosts/discovery.py
- routes/host_network_discovery.py -> routes/hosts/discovery.py
- routes/host_security_discovery.py -> routes/hosts/discovery.py
- routes/host_groups.py -> routes/host_groups/
- routes/group_compliance.py -> routes/host_groups/
- routes/scans.py -> routes/scans/
- routes/scans_api.py -> routes/scans/

Updated Services:
- bulk_scan_orchestrator.py: Updated import paths
- error_classification.py: Updated error handling, removed unused import
- rule_service.py: Updated rule query logic
- models/error_models.py: Updated error model definitions

Updated Tasks:
