Migrate from HTTP API to gRPC with cqrs_services proto

- Regenerate proto stubs from correct cqrs_services.proto file
- Update GrpcCqrsApiClient to use DynamicQueryService and CommandService
- Fix type conversions for deliveries, routes, and commands
- Convert proto Timestamp to ISO8601 strings for model compatibility
- Convert string amounts to doubles for delivery orders
- Use Int64 for delivery IDs in gRPC commands

Work in progress: Timestamp conversion extension needs finalization.
