phase 4: connectrpc on the gateway authenticated edge
Replace the native-gRPC server bootstrap with a single `connectrpc.com/connect` HTTP/h2c listener. Connect-Go natively serves Connect, gRPC, and gRPC-Web on the same port, so browsers can now reach the authenticated surface without giving up the gRPC framing native and desktop clients may use later. The decorator stack (envelope → session → payload-hash → signature → freshness/replay → rate-limit → routing/push) is reused unchanged behind a small Connect → gRPC adapter and a `grpc.ServerStream` shim around `*connect.ServerStream`.
