test(proxies): narrow delay regressions to reported failures

Remove global fake timers and deferred request scaffolding. Keep only profile-switch cache isolation and shared-key listener cleanup regressions.

 - 修复全局模式默认停在 `DIRECT` 或 `REJECT` 导致流量未经代理，现自动切换到第一个策略组
 - 修复订阅中未加引号的 REALITY `short-id`（如 `1234e123`）被误读为数字，导致订阅无法启用
 - 修复订阅中唯一的代理组名为 `GLOBAL` 或没有代理组时，规则模式下代理页面显示「未获取到代理信息」
+- 修复切换订阅后节点延迟显示旧订阅结果，进入代理页面时主动刷新延迟记录
