feat: Add Protobuf definitions for Network Membership service

- Introduced `networkmembership.proto` with RPC methods for retrieving user network tree, statistics, and position.
- Implemented HTTP annotations for gRPC transcoding in the service methods.
- Added support for Google API annotations in `annotations.proto` and `http.proto`.
- Created `ConfigureServices.cs` to register FluentValidation for the Protobuf services.
- Updated project file to include necessary dependencies for gRPC and Protobuf.
