Register or update a CIMD client via metadata URI

Idempotent registration for Client ID Metadata Document (CIMD) clients. Uses external_client_id as the unique identifier for upsert operations.

Create: Returns 201 when a new client is created (requires create:clients scope). Update: Returns 200 when an existing client is updated (requires update:clients scope).

This endpoint automatically:

• Fetches and validates the metadata document
• Maps CIMD fields to Auth0 client configuration
• Creates/rotates credentials from the JWKS
• Enforces CIMD security policies (HTTPS-only, no shared secrets)

POST https://{tenantDomain}/api/v2/clients/cimd/register
