     * [技师]获取附近技师列表
     *
     * @description 根据用户当前位置获取指定范围内的技师列表，支持分页和距离筛选
     *
     * 业务流程:
     * 1. 验证用户位置和分页参数
     * 2. 获取系统设置的最大搜索半径
     * 3. 查询指定范围内的技师
     * 4. 根据技师个人设置的接单距离筛选
     * 5. 返回分页后的技师列表
     *
     * 筛选规则:
     * - 技师必须通过基本信息认证
     * - 技师必须通过实名认证
     * - 技师必须通过资质认证
     * - 如果技师设置了接单距离，户距离必须在范围内
     * - 未设置接单距离的技师，只要在系统搜索半径内就显示
     *
     * 排序规则:
     * - 按照技师到用户的实际距离升序排序
     * - 未获取到距离的技师排在最后
     *
     * @authenticated 需要用户登录认证
     *
     * @queryParam page int 当前页码,默认1. Example: 1
     * @queryParam per_page int 每页数量,默认15. Example: 15
     * @queryParam latitude float required 用户当前纬度坐标(-90到90). Example: 39.9042
     * @queryParam longitude float required 用户当前经度坐标(-180到180). Example: 116.4074
