hscontrol: remove the proto, gRPC and grpc-gateway stack

Browse Source 
With the v1 API served by Huma and the CLI on the HTTP client, nothing
uses the gRPC service or its generated code. Delete proto/, the generated
gen/go and gen/openapiv2, grpcv1.go, the buf config, the proto .Proto()
helpers and gRPC config, and the proto build tooling from the flake and
CI.
