fix(framework): Bump grpcio to >=1.72

[danieljanes]

This PR bumps grpcio from >1.70 to >1.72 because grpcio-tools==1.70.0 has erroneous wheel metadata.

[Copilot]

Pull request overview

This PR updates the framework’s gRPC toolchain/dependencies to avoid issues with grpcio-tools==1.70.0 wheel metadata and aligns the checked-in generated gRPC stubs with the newer generator version.

Changes:

• Bump grpcio / grpcio-health-checking minimum versions to >=1.72.0,<2.0.0 and grpcio-tools to ==1.72.0.
• Update uv.lock to the newly resolved dependency set (notably including newer grpcio* and protobuf).
• Regenerate Python protobuf/gRPC modules to reflect the updated generator/runtime versions.

This regenerated *_pb2.py code now enforces a Protobuf runtime version >= 6.30.0 via ValidateProtobufRuntimeVersion (major=6). The project dependency range still allows protobuf 5.x, which would install successfully but then fail at import time for these modules. Either bump the protobuf lower bound to >=6.30.0 (keeping <7) or regenerate the protos using protobuf 5.x to preserve protobuf 5 compatibility.
