feat(lbs): 真实距离与按距离派单落地

浏览代码 
- 数据库：orders/activities 新增 latitude/longitude（含存量表 ALTER 迁移）

- 服务端：Haversine 计算 distanceKm/distanceText，派单池支持 lat/lng/radius 过滤并按距离升序；历史无坐标订单用腾讯地理编码兜底并回写缓存

- 新增 /api/lbs/reverse 逆地址解析（Key 仅服务端持有，登录 + 限流）

- 小程序：雷达/接单大厅改用真实定位与真实距离，删除全部写死演示距离；下单页新增地图选点，组局页保存选点经纬度

- 修复接单大厅点接单会新建订单的问题，改为真正 claimOrder 认领

- 新增 lbs-distance 护栏（110 套件/729 用例全绿）
