feat(api): 新增小程序用户端与后台管理端 v1 业务接口（62 端点）

一、基础设施
- route.php：58 条路由覆盖 /api/v1/**；:id 用 \d+ 约束、长路径优先
- api/controller/V1.php：响应适配为 {code,message,data}（FastAdmin 原生 {code,msg,time,data} 不兼容）；
  Authorization Bearer 鉴权；统一分页；业务公共 userInfo/ext/flow/notify/adminLog
- admin/command/FcInstall.php：19 张 fa_fc_* 表 + 种子数据，幂等可重跑

二、控制器 17 个
- 用户端 Auth/Home/Post/Member/Distribution/Message/Setting
- 后台端 AdminDashboard/AdminMerchant/AdminMember/AdminPost/AdminComment/
  AdminDist/AdminOrder/AdminFinance/AdminRbac/AdminSetting

三、契约一致性
- 字段与小程序 common/mock/data.js 逐字段对齐，Mock 与真实接口可对拍
- 实现 BR-01~BR-12，错误文案与前端 mock 完全一致
- 详情联系方式强制脱敏，付费/会员方可解锁

四、验证
- tools/verify-api.mjs：63 端点契约 + 12 条业务规则 + 8 步双端闭环
- docs/05-后端实现规范.md
