feat: add swimlanes view toggle to Kanban board

- Introduced `swimlanesByTags` filter in `KanbanFilters` to toggle between swimlanes and standard Kanban view.
- Updated `BoardContainer` to conditionally render `SwimlanesBoard` or `KanbanBoard` based on the selected filter.
- Enhanced UI with a button to switch views, improving task organization and user experience.
