新增农户功能升级：身份证OCR/OSS上传、头像采集、同名村检测、Region热度排序及表单体验优化

- Region 表新增热度列，热门省份优先显示
- 区县下拉按地级市分组、已录区县优先、支持全省搜索
- 组选择内置一组至二十组
- 银行卡号独立行+粗体预览，开户行独立行
- 新增农户类型：农户/个体户/合作社/经营集体/公司
- 身份证正反面支持高拍仪/摄像头OCR与手机扫码上传，附件存本地/OSS
- 新增农户头像采集组件（摄像头/本地上传），预留人脸识别收购扩展
- 同名村弹窗提醒（防选错乡镇）
- 编辑窗体禁止遮罩/Esc误关，整体加宽适配高频操作
- 修复二维码局域网手机无法访问（监听0.0.0.0、局域网IP识别、Vite代理兜底）
