fix: 修复 MALL 商品列表/选择器「价格」列展示原始的「分」（web-antd / web-ele）

商品列表 [mall/product/spu/data.ts] 与商品选择器 [mall/product/spu/components/spu-select-data.ts]
的「价格」列原先 formatter: 'formatAmount2'，只做了小数格式化、漏了「分转元」，导致
19900 直接显示成 19900.00（应为 199.00 元）。同文件的 marketPrice / costPrice 已正确使用
fenToYuan，唯独 price 漏了。

顺手将 spu/data.ts 的 price / marketPrice / costPrice 三列从手写闭包统一切到已注册的
formatFenToYuanAmount formatter，单位「元」从 cell 后缀挪进列标题（如「价格(元)」），
减少 8 处闭包并复用平台统一的 null/NaN 处理。
