Delete Tenant Identity Configuration

Delete the tenant identity configuration and destroy the per-org signing keypair.

User must have authorization role with TENANT_ADMIN suffix in the URL {org}.

After DELETE, JWKS and OIDC discovery for this org begin returning 404; previously-issued JWT-SVIDs become unverifiable once consumers refresh their JWKS cache. To pause issuance without destroying signing keys, PUT with enabled: false instead.
