feat(filter): add maximum selection limits for checkbox filters
Implement a maxOptions property to limit the number of selections in checkbox filters.
This feature includes FIFO behavior for managing selections and hides the "Select All"
control when limits are set to prevent user confusion. Update related documentation
and components to reflect these changes.
