/**
 * Owner-side administration of the staff accounts inside the active company.
 *
 * The controller settles who may act and hands everything else on: the form
 * request shapes the payload and the service owns every write. Ownership is
 * positional and re-read on each call, so the same person administers members
 * under one `company` header and is refused under the next.
 *
 * Note that the single-account routes bind their model installation-wide — an
 * id belonging to another tenant resolves perfectly well and is turned away by
 * the policy rather than by a missing row, which is a 403 where a 404 might be
 * expected. Kept as it stands.
