Function renderCozystackWith

pkg/engine/render_test.go:6834–6864

renderCozystackWith renders the cozystack controlplane template against the supplied LookupFunc and values overrides, returning the final template output or failing the test. Mirrors the pattern used by the existing TestMultiDoc* suites.

(t *testing.T, lookup func(string, string, string) (map[string]any, error), overrides map[string]any)
