v1.20.9

Fixes

• Simplified claiming QR codes now include the full public redemption URL, including the domain.
• Copied links and downloaded QR SVGs use the same full URL.
• Added regression coverage for QR images, downloaded SVGs, and copied links, and validation that rejects relative redemption URLs.

Previously downloaded or printed QR codes must be replaced after deployment.
