fix: 修复多个API通信和数据展示问题

- 修复仓库容器parent_id/物品container_id为null导致Gson反序列化失败
- 修复ScheduleApi参数名与后端不匹配
- 修复Profile页面username空字符串导致显示未登录
- 修复Retrofit Map类型参数编译后变为通配符被拒绝
- 修复ScrollableTabRow动态tab数量变化时IndexOutOfBounds崩溃
- 修复仓库新建容器字段名name→title匹配后端
- 修复新建物品传入错误的containerId
- 所有页面改为下拉刷新，去除首页自动刷新
- 新建工单支持关联物品/客户/图片上传
- 新增物品表单包含数量/关联客户/图片上传
- 物品详情页重构：基本信息/图片/关联工单/客户/移动历史/移动/删除/新建工单预填
- 打印模块添加黑标检测、Mutex并发锁、delay替换Thread.sleep
