Description

This PR enhances the popup functionality by migrating from a traditional HTML/CSS/JavaScript-based implementation to the native Popover API.

Problem:

The application already had existing Popover API usage in both the sidebar and crossword components. When I attempted to implement the Popover API for the popup, it caused conflicts—particularly due to overlapping behavior with the sidebar.

Solution:

To resolve this, I referred to the crossword component's popover implementation, rewrote the popup logic accordingly, and separated its logic cleanly from the sidebar. I also fixed minor bugs and enhanced responsiveness and styling for a more consistent user experience across devices.

Fixes: optimized popup rendering and popover conflict issue
