* Step-1 hotfix regression tests for the Settings API fetch guard.
*
* The reported "Unexpected token '<', "<!doctype "... is not valid JSON" error
* came from parsing the SPA's index.html as JSON when a Settings API route was
* not forwarded to the backend. fetchApiJson must turn that into an actionable
* message and never throw a raw JSON.parse error.
