Same screen contract, but the data flows from DataManager.allTasks
through a combine(_allTasks, _currentResidenceId) into the existing
StateFlow. No per-residence network call needed; the upstream
getTasks() refresh propagates and the screen re-renders.
Eliminates the gitea#2 race window on Android — same fix as the iOS
TaskViewModel commit. Both platforms now react to _allTasks changes
without manual refresh.
