This task summarizes the PR to move recent GraphQL work from an experimental branch into Sagitta. The PR will need to be merged before those implementing support for the standardized op-mode scripts (T4544; T4554).

The PR includes several commits added to support the local-UI development: support for REST style key authorization; CLI nodes for GraphQL support; addition of a 'SystemStatus' query as a test case for the local-UI client; extension of the smoketest 'test_api_auth' in 'test_service_https.py' to GraphQL. It has seen regular use/testing during development of the local-UI client.
