Frontend changes:
- Add generic WithSummaryResponse<T> model for CRUD responses
- Update TaskApi, TaskCompletionApi, ResidenceApi return types
- Update APILayer to extract summary from responses and call DataManager.setTotalSummary()
- Replace refreshTasks() calls with DataManager.updateTask() for local cache updates
- Remove redundant refreshMyResidences() calls
- Remove unused helper methods (refreshTasks, refreshMyResidences, refreshSummary)
- Add summary field to JoinResidenceResponse model
This pairs with the backend changes to eliminate redundant network calls
after CRUD operations - dashboard stats now update from the mutation response.
