Surface gRPC failure context to Python script authors instead of
silently returning sentinel values or raising bare gRPC errors.
- RipsError now carries code/details/location and a from_rpc_error()
helper. Existing single-arg construction stays valid.
- Stop swallowing grpc.RpcError in case.__grid_count for non-NOT_FOUND
failures and in instance._check_connection_and_version, so the
underlying status is propagated.
- pdmobject add_method decorator and _call_pdm_method_* attach
code/details to the raised RipsError; existing message text is
preserved so pytest match=... assertions keep working.
- Instance.start_heartbeat / stop_heartbeat / check_alive provide an
opt-in background ping that flips a sticky lost-connection flag and
raises a readable RipsError from check_alive() if the server dies.
- Server side: GetPdmObject in RiaGrpcAppService, RiaGrpcCaseService
and RiaGrpcProjectService no longer return Status::OK with an empty
reply when the underlying object is missing; they return NOT_FOUND
/ INTERNAL with a descriptive message. Other RiaGrpc*Service files
audited and already return non-OK with text on error paths.
