Remove summary from list responses, calculate client-side

- Remove summary field from MyResidencesResponse and TaskColumnsResponse
- Update HomeScreen and ResidencesScreen to observe DataManager.totalSummary
- Load tasks when residence views appear to ensure accurate summary
- Add pull-to-refresh for tasks on ResidencesScreen
- Update iOS views to use client-side calculated summary

Summary is now calculated via refreshSummaryFromKanban() from cached
kanban data. This ensures summary is always up-to-date after CRUD
operations and when residence views are shown.
