fix(panels): 12116 - add modal view for panels in mobile mode and differ it from collapse state

[IlyaIzr]

Not sure whether i should make

{isOpen && isMobile ? (
        <Modal onModalCloseCallback={onPanelClose} className={s.modalCover}>
          {panel}
        </Modal>
      ) : (
        panel
      )}

as a component. Should I?

Examples:
