fix(sidecar): align grpc-netty/grpc-okhttp with grpc-core version

Maestro 1.40.0 brings grpc-netty:1.50.2 which compiled against
AbstractManagedChannelImplBuilder, removed in grpc-core 1.64+.
Gradle was upgrading grpc-core to 1.68.0 while leaving grpc-netty at
1.50.2, causing NoClassDefFoundError at startup.

Force grpc-netty and grpc-okhttp to match grpcVersion so all gRPC
artifacts are binary-compatible.
