/**
 * 红娘工作台主页
 *
 * ZC-MM-002（A1 / DEC-MATCHMAKER-002 锁定决策）：
 * - 普通红娘禁止认领（原 POST /services/{id}/claim 端点已删除），本页不再有任何接单逻辑；
 * - 列表数据源从 GET /operator/matchmaker/pending（现仅分配权持有者可调，普通红娘 403）
 *   改为 GET /operator/matchmaker/assignments/my（仅返回本人生效中的服务对象分配）。
 *   响应为 assignment 字段（userId/assignmentReason/status/assignedAt/serviceId 等），
 *   无服务类型/诉求描述字段，故按实际字段精简展示，不前端拼空值。
 *
 * 展示待处理服务、工作台数据概览
