### Description

On my first try with a non-existent application name,'shore -v save' -> gave the logs indicating the pipeline is created and no error message.

When I retry the same command, Shore detects that the specific pipeline already exists in the application and creates a new pipeline while saving the existing pipeline with a new Id.

It will be beneficial if application name validation is available.

### Additional Information

Start by reproducing `shore -v save` with a non-existent application name and inspect the save command's application lookup path. Done means the command reports that the application was not found and does not create or duplicate a pipeline.
