feat: reintroduce ColumnVisibilityToggle in KanbanFilters

- Moved `ColumnVisibilityToggle` from `Board` and `SwimlanesBase` to `KanbanFilters` for better accessibility.
- Updated `KanbanFilters` to manage column visibility, enhancing user control over displayed statuses.
- Cleaned up unused imports and adjusted layout for improved UI consistency.
