feat: add click-to-copy interaction to QR code #2851

[keshav0479]

Description

This PR implements the "Click-to-Copy" functionality for QR codes as requested in #2851.

Changes

• Wrapped the QRCode component in a clickable container.
• Added a hover overlay with a PopiconsCopyLine icon using Tailwind group-hover for zero-state logic.
• Implemented pointer-events-none on the center Avatar in the Receive screen to ensure the entire QR area is clickable.
• Used the existing copied translation key and internal toast component to maintain consistency.

Note

This PR addresses and resolves the feedback provided in the stale PR #3345 (inactive since May 2025).

Testing

• Verified hover state appears correctly in light/dark mode.
• Verified clicking anywhere (including the center logo) copies the address and shows the toast notification.
