Issue a digital badge via the Credly API and configure duplicate-behavior policy for repeat earners

Steps

1. Authenticate to the Credly API using HTTP Basic Auth with your API key; all requests go to https://api.credly.com/v1/ per the developer docs at https://www.credly.com/docs/getting_started
2. Retrieve the target badge template ID via GET /organizations/{organization_id}/badge_templates to map your internal certification name to a Credly template
3. POST to /organizations/{organization_id}/badges with body fields: badge_template_id, issued_to_first_name, issued_to_last_name, recipient_email, and optionally issuer_earner_id (your internal user ID for reconciliation)
4. Set duplicate_behavior to 'replace' if you want the new issuance to supersede a previous one, 'deny' to block duplicates, or 'allow' to permit multiple badges; note this only applies when the template's allow_duplicate_badges is false
5. Handle the suppress_badge_notification_email=true flag to suppress Credly's default email and send your own branded notification
6. Check the returned issued badge object for state field; value 'accepted' means the earner has already claimed it; 'pending' means awaiting acceptance
