请假/销假全部入口补齐独立学工系统分流，修复点销假仍报 420

问题：上一版只在 GetLeaveTypes 加了 xsgz/xsfw 分支，其余请假入口仍走辅导猫
旧链路。用户点销假按钮（走 /leave/pending-list）时仍拿到辅导猫的 HTTP 420
「产品已到期」，提示误导且无法自助解决。

改动：新增 rejectExternalLeaveSystem 统一守卫，接入全部 7 个请假相关入口：
- GetLeaveTypes / GetLeaveApplyApprovers / ExecuteLeaveApply（请假侧）
- GetPendingLeaves / GetLeaveApprovers / ExecuteLeave（销假侧）
- GetLeaveExtendPrefill（续假）
命中 xsgz/xsfw 时短路返回明确文案「XX大学 的请假由学校「学工系统」独立提供，
不支持在今日校园内提交，请前往学校学工系统办理」，不再让用户看到 420。

新增单测验证分流判定与文案（纯静态映射，不触发网络）。

+//  1. SendSmsCode(phone)         → 今日校园下发短信验证码

+//  3. ExchangeCasCookie(loginData)   → 用 sessionToken 换取学校 CAS cookie（含 MOD_AUTH_CAS）
+//
+// 该 cookie（含 CASTGC，长期有效）后续可反复换取 CAS cookie，即「长期凭证」。
+// 加密方式与项目既有 crypto.go 一致（AES-128-CBC / DES-CBC，PKCS7）。

+// 老内核兼容后处理（构建期执行）：
+//
+// 背景：Tailwind v4 的产物大量使用较新的 CSS 能力，老内核（国产浏览器/微信内置
+// 内核，实测线上存在 Chrome 78/85/91/97）会丢弃不认识的部分，表现为“只剩基础
+// 元素、没有样式”。逐项处理如下：
+//
+//   ① CSS 级联层 @layer（Chrome 99+）：老内核不认识该 at-rule，会把整块工具类
+//      直接丢弃 —— 这是“无样式”的主因，必须剥离；
+//   ② oklch() 颜色（Chrome 111+）：降级为十六进制色值（lightningcss）；
+//   ③ :where() 选择器（Chrome 88+）：其特异性为 0 的设计依赖较新引擎，
+//      老内核整条规则丢弃；解包为等价选择器（保持原有特异性位置）；
+//   ④ JS 语法（可选链等）由 vite build.target 统一降级，不在此处处理。
+//
+// 处理顺序：先解包 :where（lightningcss 不处理它），再整体按目标内核降级，
+// 最后剥离 @layer 并做完整性校验。
