fix: 修复全部27个失败的e2e测试

根本原因: 所有测试硬编码了只在生产环境有效的admin token，
CI创建新数据库时token不同导致全部认证失败。

修复:
- CI: 设置已知ADMIN_TOKEN环境变量传给后端和Cypress
- cypress/support/e2e.js: 新增cy.getAdminToken()动态获取token
- 24个spec文件: 硬编码token改为cy.getAdminToken()
- UI选择器: 适配管理页面从tab移到UserMenu、编辑器DOM变化
- API: create_recipe→share_recipe、ingredients格式、权限变化
- 超时: 300s→420s适应32个spec
