feat: code-first navigation — use resource codes in links and displays

- DashboardPage: show task_code instead of #id, link via code
- TasksPage: navigate to tasks via task_code
- MilestoneDetailPage: navigate to tasks/supports/meetings via codes
- MilestoneDetailPage: display codes in support/meeting tables
- Fix support/meeting state types to any[] for code property access
