feat: add column visibility toggle to Kanban and Swimlanes boards

- Integrated `useColumnVisibility` hook for managing column visibility states.
- Added `ColumnVisibilityToggle` component to both `KanbanBoard` and `SwimlanesBoard` for user control over visible columns.
- Updated rendering logic to filter and display only visible columns, enhancing user experience and task organization.
