fix(FN-2577): preserve Todos access and TodoView interaction behavior

- Keep the view overflow trigger available when Todos is supported so the Todos view remains reachable
- Update TodoView list rows to use an explicit select button and align active-state assertions with the new structure
- Restore keyboard focus styling and mobile action visibility in TodoView CSS for accessibility and usability
- Harden CLI extension test cleanup with retry logic for transient ENOTEMPTY/EBUSY tempdir removal errors
