feat(wallet): 解绑微信前对待审核提现二次确认 (#46)

## 改动
解绑微信前若有**待审核(reviewing)**提现单,首次解绑被拦下返回二次确认,用户确认后带 `force=true` 才真解绑。

- `schemas`: `UnbindWechatRequest{force}` + `UnbindWechatResultOut{needs_confirm, message}`
- `repositories`: `has_reviewing_withdraw`(只看 reviewing)
- `api`: `unbind-wechat` 接受可选 body(兼容旧无 body 客户端);`bound` 返回真实绑定态
- `docs/api`: 同步协议

## 为什么只拦 reviewing
reviewing 单解绑后审核打款会回读空 openid → 自动退回现金(钱不丢、只为让用户知情);pending 转账已在途、解绑影响不到,不拦。

配套客户端见 shaguabijia-app-android 同名分支。
