精简版第四轮补裁(P4): 页面层摘除 + Xray更新端点下线 + 本机核心监管下线

页面层(用户真机截图发现前两轮漏裁): - 设置: 摘除 Telegram机器人/邮件菜单与页面, 及页内残留入口(通知页/外部流量/LDAP/2FA设置页) - Xray配置: 摘除负载均衡/DNS/高级配置菜单与页面; 基础配置(出站+路由)完好 - 总览: 摘除 Xray更新弹窗(VersionModal+GeodataSection)全部入口, 版本号改为静态展示 - 13个locale同步摘除461个已删功能专属翻译键(逐键核查前后端引用为零; i18n-dead-keys测试全绿) Xray更新后端(经调查确认仅服务本机bin/xray, 与agent下发/订阅无关): - 删除 getXrayVersion/installXray/updateGeofile 路由与handler(访问返回404) - 删除 ServerService 对应实现与校验和函数; 同步api-docs/monitor白名单/openapi 本机核心监管下线(设计: 主控永不运行本机xray, 入站全在agent): - XrayService.RestartXray 降级为no-op(一次性Warning说明日志); StopXray无进程时幂等返回 - web.go 摘除启动拉起本机核心/CheckXrayRunning看门狗(1s)/ApplyPendingRestart cron(30s)/XrayTrafficJob/CheckClientIpJob 注册 - ApplyPendingRestart 降级为消费即清, 其测试更新为新语义 - XrayMetricsService.Sample 短路: 不再每2s探本机/debug/vars, 状态优雅置为不可用 - 配置生成(纯JSON)/agent链路/订阅/入站CRUD未动; 状态读数优雅归零(stop/Unknown) 注: TestGetXrayConfig_EnabledClientsStillEmitted 在基线945b3a5同样失败(既有问题, 非本轮引入)
