api 补齐 6 个驼峰路径别名，与 PHP 路由对齐

- uniapp 客户端沿用 PHP 的驼峰 action（goods/specData、order/todoCounts 等），
  而 Java 端只映射了下划线形式，实测返回「接口未实现」
- 用 value 数组同时挂两种写法，下划线形式保留（测试脚本仍在用），零破坏：
  - /api/address/default_id | /defaultId
  - /api/address/set_default | /setDefault
  - /api/goods/spec_data   | /specData
  - /api/goods/sku_info    | /skuInfo
  - /api/comment/list_rows | /listRows
  - /api/order/todo_counts | /todoCounts
- 实测 uniapp api 目录 72 个路径，未实现数由 8 降到 2（剩余 order/pay、
  user.coupon/receive 是前端死代码，页面未调用）
- 回归 test_api_batch1 52 项全过
