* EDC-V / CFM API Client
*
* Type-safe client for all JAD Management, Identity, Issuer, Tenant, and
* Provision Manager APIs. Uses openapi-typescript generated types with
* a lightweight fetch wrapper.
*
* Usage:
* import { edcClient } from '@/lib/edc/client';
*
* // List all assets for a participant
* const assets = await edcClient.management(
* '/v5alpha/participants/{ctxId}/assets/request', 'POST',
* { '@context': [EDC_CONTEXT], '@type': 'QuerySpec' }
* );
*
* // List tenants
* const tenants = await edcClient.tenant('/v1alpha1/tenants');
*
* Types are generated from JAD OpenAPI specs via:
* npm run generate:api
*
* @see {@link https://github.com/Metaform/jad} JAD repository
