Adds a narrow IDataManager contract covering the 5 DataManager members referenced from ui/screens/** (currentUser, residences, totalSummary, featureBenefits, subscription) and a staticCompositionLocalOf ambient (LocalDataManager) that defaults to the DataManager singleton. No screen call-sites change in this commit — screens migrate in P0.2. ViewModels, APILayer, and PersistenceManager continue to depend on the concrete DataManager singleton directly; the interface is deliberately scoped to the screen surface the parity-gallery needs to substitute. Includes IDataManagerTest (DataManager is IDataManager) and LocalDataManagerTest (ambient val is exposed + default type-checks to the real singleton). runComposeUiTest intentionally avoided — consistent with ThemeSelectionScreenTest's convention, since commonTest composition runtime is flaky on iosSimulator.
