I uploaded a broken calendar UI component. Please fix the layout and styling so that:

The calendar is fully visible and not cut off or overlapping other elements.

The date cells are aligned correctly in a grid (7 columns for days of the week).

The navigation (for switching months) works and is styled properly.

Text is readable and responsive on mobile and desktop.

This looks out of place and misalligned with the interface and when you click on it the lateral side bar opens up, that shouldnt happen. We need one button for calendar
