- Add required email field to registration form (was missing entirely,
causing "N/A" emails in booking notifications)
- Pass email through full chain: form → API → Google Sheet → Mollie
metadata → webhook (with Mollie billingAddress as fallback)
- BCC contact@cryptocommonsgather.ing on all payment confirmation
emails so team is notified of every successful registration
- Replace OG image with alpine mountain card including event name,
dates, and URL for better Twitter/social sharing
