defaultLabelRes

Presentation-edge mapping from an OperationKind (domain state) to its localized DEFAULT label resource (#259) — used for the ongoing foreground-service notification when the caller didn't supply its own label (i.e. the SDK's own built-in send / dust / contract operations). A caller-provided label always wins; this is only the fallback. The exhaustive when fails to compile if a kind is added without a label, so the centralization stays honest.

Mirrors SyncPhase.labelRes; the SDK emits the enum, the host renders the string (and can override these resources).
