refactor: update Kanban components for improved layout management and persistence

- Removed the teamName prop from KanbanGridLayout to streamline component usage.
- Renamed GRID_SCOPE_PREFIX to GRID_SCOPE_KEY for clarity in layout management.
- Introduced LoadedKanbanGridLayout for better separation of concerns in rendering.
- Enhanced the usePersistedGridLayout hook to improve layout persistence handling.
- Updated KanbanBoard to utilize the new LoadedKanbanGridLayout, improving task organization.
