feat(face): 支持按userFaceId查询单条人脸记录

- FaceDao新增queryByUserFaceId接口，实现按userFaceId精确查询
- FaceApi新增queryByUserFaceId方法，封装Dao查询逻辑
- LoginByFaceActivity插入人脸时，先按userFaceId查询，存在则更新避免重复
- NetViewModelV2同步人脸数据时，优先用userFaceId判重，减少重复入库
- 修正FaceEntity中userId字段数据库列名错误（user_id替代user_idd）
- 增加注释说明及代码格式优化，提升代码可读性和健壮性
