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.
