task-69(ASIN 数据中心): 实现品牌数据库新增/编辑表单

invalid-asin-form-model.ts 纯模型：createEmptyInvalidAsinForm/invalidAsinFormFromItem 回填、
validateInvalidAsinForm 镜像后端(ASIN 必填<=128/品牌<=128/manual 必选分组)、toCreate 请求(camel)、
toUpdate 请求(自动导入默认不迁组)；invalid-asin-api.ts 增 createInvalidAsin POST 与
updateInvalidAsin PUT /api/admin/invalid-asin-data。8 用例全过，507 单测 + build 绿。
