test(ui-guards): 导航契约守卫基线对齐后端真实权限码

- admin-role-navigation-contracts.mjs L40-41 原断言 referral.manage /
  matchmaker.service.view，但后端 permissions 表不存在这两个幽灵码——
  v1.1.1 权限码对齐（4edb761）时漏更新守卫基线，导致该守卫自 v1.1.1 起恒红
- 修正为后端真实 authority 码：/referral→matchmaker.service、
  /matchmaker→matchmaker.view（守卫内容修正，非删守卫，MIN_GUARDS 不变）
- 实测 UI 契约 24/24 全绿
