[Accessibility]: Modal Interaction Features -> Clickable Overlay and Escape Button Closure

[Spiral-Memory]

As an EmbeddedChat developer

I need to: Implement a functionality wherein, if a modal is currently open, clicking on the backdrop/overlay or pressing the Escape (Esc) button will automatically close the modal.

So That: Users can effortlessly manage popups, giving them a more intuitive and user-friendly interaction.

Acceptance Criteria

• [✓] Modal should close when clicked on the overlay (Modal backdrop).
• [✓] Modal should close when the Escape (Esc) button is pressed on the window.
• [✓] Proper flow of props, refs, and using dependencies array to prevent unnecessary re-renders.
