GPU显卡公共参数字段全面升级为66字段+字段类别支持

- 按显卡规格9大类别整理66个公共参数字段（全部文本类型）:
  图形处理器芯片基础信息(14)/显卡产品信息(12)/渲染硬件配置(8)/理论算力(5)/显存规格(5)/矩阵算力(8)/数值格式支持(2)/图形API与特性(6)/板卡设计(6)
- 每个字段新增 category 字段类别属性（对应#开头的参数类别中文名）
- 保留平台必备结构字段: name/manufacturer/official_urls/reference_urls/description
- 后台字段编辑弹框新增「字段类别」输入，字段列表显示📁类别徽标
- 子类别关键特性映射到新字段(显存容量/着色单元/首发价/FP32等)
- 修复重复FP16: 理论算力=fp16, 矩阵算力=fp16_matrix
