[Bug] Fix workspace CLI Command

[shinybrar]

• When doing a workflow workspace set command
  • Make the configuration folder to be ~/.config/workflow/workspace.yaml filename
  • Do not copy the source, from wherever you get it, to the the ~/.config/workflow/ folder at all

The general idea is, we will ship some configs, but we will also let people set configs, via a URL provided during workflow workspace set https://workflow.config.yaml

• Write tests, if not already to make sure the new folder location is always clean.
• Additionally, break all locations where workspace is used, e.g. in the Work, HTTPContext etc. objects, and raise a clear exception, Pydantic FilePath Error informing the user to run the workflow set command from the HTTPContext
