Backend: Add global Catalog arguments to GraphQL

Problem

The ciCatalogResources query currently takes a projectPath and returns catalog resources published in the project's root namespace.

We need to update it for the new General Catalog.

Proposed solution

Add an optional scope argument to the query. scope can be either all or namespaces. In the future it will also have official and community options.

• When scope is not present or all: return all CI Catalog resources visible to the current user
• When scope is namespace: return resources published in namespaces to which the current user belongs

Note: we can remove the projectPath argument once the frontend has started using scope
