feat(explore-attr-breakdowns): Adding chart tooltip actions

[Abdkhan14]

The behaviour that we are going for is:

• When hovering, show tooltip + display 'Click for actions' placeholder
• Click to freeze the position of the tooltip + display actions
• Click again to restore default tooltip state

---

• Echarts does not allow position freezing + actions on the tooltip out of the box, so I had to do it manually.
• Added ample comments on the new hook, please reach out if anything is confusing!
• NOTE: Don't worry about duplication, I'm working on a consolidation PR next.

Bug: Unconditional preventDefault blocks all document clicks

The handleClickActions event handler calls event.preventDefault() unconditionally at line 105, before checking if the click target has tooltip action attributes. Since this handler is attached to document when the tooltip is frozen, it prevents the default behavior for ALL clicks anywhere on the page—not just clicks on tooltip actions. This could break link navigation, form submissions, checkbox toggling, and other interactive elements outside the chart area while the tooltip is in its frozen state. The event.preventDefault() call should be moved inside the if (action && value && key) conditional block.
