The api stub from 43be32bbd silenced the fetch-rejection path but the suite
still failed on CI: the actual unhandled error is React's scheduler firing
deferred work via setImmediate after jsdom is torn down — its internal
render then dereferences `window` and throws ReferenceError. @testing-library
only auto-registers cleanup() when vitest `globals: true` is set, and this
package doesn't enable globals, so the React tree from each render() stays
mounted across teardown. Register cleanup manually in test-setup.ts so every
dashboard test unmounts its tree before the environment tears down.
