fix: 字号恢复正常大小、下架改用api.post、翻译编辑器预填充

精油价目:
- 字号恢复固定大小(14/10/13/11px)，手机端@media缩小
- 不再用clamp()（之前太小）
- 下架改用 api.post 替代 api() raw fetch，更可靠
- 稀释比例/使用禁忌卡片: emoji和标题合并为一行(flex row)

翻译同步:
- 打开翻译编辑器时预填充: 读取 oilsMeta.enName → oilEn() → 填入输入框
- 用户看到当前英文名，修改后保存到 oils.en_name
- 精油价目页 getEnglishName 读同一字段，自动同步

翻译表:
- 补充 舒缓→Deep Blue 等常用精油英文名
- oilEn() 支持去掉/添加"复方"后缀匹配
