fix: 多项修复 — 滴数框/零售价显示/精油英文名保存/再次审核通知

1. 编辑配方的滴数输入框从 42px 加宽到 58px，确保 50.5 不被 spinner 遮挡
2. 配方卡片在零售价==会员价时也显示零售价（之前因 retail>cost 过滤掉）
3. 精油价目英文名保存后被静态 OIL_CARDS 覆盖，把 getEnglishName 的优先级改
   为先用 DB meta.enName，解决温柔呵护/仕女呵护等显示不更新的问题
4. 再次审核 tag 的配方被非管理员修改时，给管理员发通知，内容含前后 diff
5. 对应 vitest + cypress 测试各一组
