Upgrade Device from Python 3.9 to 3.13.
The image now builds on python:3.13-slim with common_requirements_py313.in so grpcio and protobuf match Context and Service. cryptography, paramiko, numpy, and pandas are bumped to 3.13-capable releases, p4runtime stubs are regenerated for protobuf 6, and the Deployment uses native gRPC probes instead of grpc_health_probe.
