[frontend] - Add QR code copy-to-clipboard button in wallet deposit modal

[Hydrax117]

Description

QRCode.tsx renders a QR image but users on desktop have no quick way to copy the wallet address. They must manually type or screenshot the address.

Acceptance Criteria

• A "Copy address" button appears below the QR code.
• Clicking copies the full wallet address to the clipboard using the Clipboard API.
• Button text changes to "Copied!" for 2 seconds, then reverts.
• Falls back to a <textarea> select-all approach if the Clipboard API is unavailable.
