Fix file references after repository reorganization

Updated references in:
- deploy/deploy-onprem.sh: Fixed paths for test-deployment.sh and test_dashboard_local.py
- deploy/validate-deployment.sh: Fixed path for test-e2e-deployment.py
- tests/integration/test-e2e-deployment.py: Fixed paths for mock servers

All file references now point to correct locations in the new organized structure
