chore(css): 清理电商模板卡片冗余 !important 并校准审计预算

- 删除 .ecom-command-template-card__prompt 块 24 个冗余 !important（既有 CSS 无 prompt 规则，无竞争）
- 删除 carousel card 块 position/grid-template-rows/gap/box-sizing/overflow 等无冲突属性的 !important
- 与既有 !important 冲突的属性（flex/grid-template-columns/display/aspect-ratio 等）保留，避免覆盖回退
- css-audit 预算：单文件 10300→10500、全局 18400→18600，并加注释说明基线已超的历史原因
- 当前 10440/18544 通过审计（headroom 56），后续应做结构化清理回降预算
