feat: 大量管理配方和搜索改进

- 存为我的：修复调用错误API，改用 diaryStore.createDiary
- 存为我的：同名检测（我的配方 + 公共配方库）
- 我的配方：使用 RecipeCard 统一卡片格式
- 管理配方：按钮缩小、编辑时隐藏智能粘贴、精油搜索框支持拼音跳转
- 管理配方：批量操作改为按钮组（打标签/删除/导出卡片/分享到公共库）
- 管理配方：我的配方加勾选框、全选按钮、编辑功能
- 搜索：模糊匹配 + 同义词扩展（37组），精确/相似分层显示
- 搜索：无匹配时通知编辑添加，搜索时隐藏无匹配的收藏/我的配方区
- 搜索：配方按首字母排序
- 共享审核：通知高级编辑+管理员，我的配方显示共享状态
- 通知：搜索未收录→已添加按钮，审核类→去审核按钮跳转
- 贡献统计：非管理员显示已贡献公共配方数
- 登录弹窗：加反馈问题按钮（无需登录）
- 精油编辑：右上角加保存按钮，支持回车保存
- 后端：新增 /api/me/contribution 接口
