     * 获取附近技师列表
     *
     * 业务流程：
     * 1. 验证用户身份和状态
     * 2. 获取系统设置的最大搜索半径
     * 3. 使用Redis GEO功能查询范围内的技师
     * 4. 过滤并验证技师认证状态
     * 5. 根据技师接单距离设置筛选
     * 6. 计算并排序技师距离
     * 7. 返回分页后的技师列表
     *
     * 技术实现：
     * - 使用Redis GEORADIUS命令进行地理位置查询
     * - 使用Eloquent关联加载技师信息
     * - 实现基于距离的排序
     * - 支持分页功能
     *
     * 数据处理：
     * - 技师位置数据存储在Redis中
     * - 技师基本信息从数据库获取
     * - 认证状态多表关联验证
     * - 接单距离设置验证
     * - 距离数据格式化(保留2位小数)
     *
     * 筛选条件：
     * 1. 技师认证状态检查
     *    - 基本信息认证通过
     *    - 实名认证通过
     *    - 资质认证通过
     * 2. 距离筛选
     *    - 有设置接单距离：用户距离 <= 设置值
     *    - 无设置接单距离：在系统搜索半径内即可
     *
     * 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
     *
     * 异常处理：
     * - 用户未登录/状态异常
     * - Redis连接异常
     * - 无效的地理坐标
     * - 设置项未找到
