feat: add swimlane mode selection to KanbanFilters and BoardContainer

- Introduced `swimlanesMode` in `KanbanFilters` to toggle between 'tags' and 'priority' swimlanes.
- Updated `KanbanBoardContainer` to conditionally render `PrioritySwimlanesBoard` based on the selected mode.
- Enhanced UI to include dropdown for swimlane mode selection, improving user experience in task organization.
- Adjusted `TasksContext` to persist swimlane mode preferences, ensuring consistent behavior across sessions.
