fix: intercept all pointer events on Show Panel button, not just click

driver.js registers capture-phase handlers on document for pointerdown,
mousedown, pointerup, mouseup AND click. All call stopImmediatePropagation.
We now intercept all five event types on window capture phase to fully
own the event chain for [data-open-panel] button interactions.
