fix: 修正零售价架构错误 + 清理旧微信配置 + 归档提案 + 前端接口文档

1. 修正 retail_price 架构：
   - 删除 batch-pricing 接口的 pricing_target 字段和 retail_price 分支
     （上级只能改下级成本价，不能改零售价）
   - 新增 PATCH /api/admin/packages/:id/retail-price 接口
     （代理自己改自己的零售价，校验 retail_price >= cost_price）

2. 清理旧微信 YAML 配置（已全部迁移到数据库 tb_wechat_config）：
   - 删除 config.yaml 中 wechat.official_account 配置节
   - 删除 NewOfficialAccountApp() 旧工厂函数
   - 清理 personal_customer service 中的死代码（旧登录/绑定微信方法）
   - 清理 docker-compose.prod.yml 中旧微信环境变量和证书挂载注释

3. 归档四个已完成提案到 openspec/changes/archive/

4. 新增前端接口变更说明文档（docs/前端接口变更说明.md）

5. 修正归档提案和 specs 中关于 pricing_target 的错误描述
