Workspace roles
Set per workspace.
In practice:
- Changing settings. Owner and manager.
- Adding or removing prompts and competitors. Owner, manager and editor.

- Inviting people. Owners and managers can invite anyone; editors can invite reviewers and viewers only.
- Deleting the workspace. Owner alone.
