feat(web-modules): add per-trigger alerting switch (search + checkboxes) to WeCom Center

 一个自包含、多语言的 Zabbix 7.4 前端模块（custom module / plugin）。加载后会在 **Administration → WeCom Center** 增加一个定制页面，集中处理：
 
 - **告警优化（核心）**：以勾选方式一键切换“是否告警”与通知严重度；内置 5 套告警方案（标准 / 警告以上 / 全部 / 仅灾难 / 关闭），点一下立即生效。
+- **触发器告警开关**：按名称搜索触发器，勾选 = 启用告警、取消勾选 = 停用该触发器（写 `trigger.status`，0 启用 / 1 停用）。由于单套环境常有数万个触发器，需先输入关键字搜索（最多显示 200 条）。
 - **机器人与账号**：在同一页编辑企业微信 Webhook 地址 / 机器人 key、机器人账号、接收目标，并可“发送测试”验证（直接调用企微接口，返回 errcode）。
 - **模板导入**：把放在 `templates/` 目录里的模板文件（yaml/xml/json）一键导入 Zabbix。
 - **地图坐标**：批量/单个设置主机的 `location_lat` / `location_lon`（主机资产清单）。

 - `manifest.json` 用 `manifest_version: 2.0`；action 的控制器类位于 `actions/`（自动加载器会把子命名空间段转小写）。
 - 视图目录必须在 `Module::init()` 里 `CView::registerDirectory($this->getRelativePath().'/views')`。
 - 菜单注入：`APP::Component()->get('menu.main')->findOrAdd(_('Administration'))->getSubmenu()->add(...)`。
