Fix eye button tap on touch devices in details panel

Browse Source 
On touch devices, tapping an eye button in the details panel would
trigger chart mouseout → showDefaultView() which rebuilt the DOM
before the click event fired. Added pointerdown/pointerup guards
on the details box to prevent the race condition.

Also added @media (pointer: coarse) to always show eye buttons
on touch devices regardless of viewport width.
