/**
 * Service Customers API (`users/admin/customers`).
 *
 * Two guarded surfaces on one controller prefix: `/users/admin/*` is
 * and only opts in/out of them. The provider is resolved from the JWT, never
 * from a path param.
 *
 * The backend validates with `forbidNonWhitelisted: true`, so undefined params
 * are stripped before sending — an explicit `undefined` would serialize away
 * anyway, but an empty `search=""` would not, and the backend would treat it as
 * a real (always-matching) filter. Boolean filters are declared
 * `@IsBooleanString` backend-side, so they go over the wire as "true"/"false".
