feat: 实现供水运营专题大屏BI可视化

- 新增OperationDashboard.vue全屏大屏组件
- 添加6个核心KPI指标卡片: 进水总量/出水总量/产销差率/营收额/平均水质/报警次数
- 实现6个ECharts图表: 供水趋势/水质分布/报警统计/管网空间/设备状态/营收分析
- 创建静态HTML版本operation-dashboard.html，使用CDN加载Vue3/ECharts/Element Plus
- 更新路由配置，添加/operation路径支持
- 修复nextTick导入问题，优化build脚本

+# Prebuilt zip.js bundles
+
+**Note**: These bundles are not ES module compatible (you cannot `import` them directly). Use `index.js` at the project root or one of the `zip-*.js` files in [`/lib`](../lib) (e.g. `/lib/zip-core.js`) for ESM usage.
+
+Contents:
+
+- `zip.js` / `zip.min.js`: Full `ZipWriter` / `ZipReader` bundles with embedded Web Worker code and WASM.
+- `zip-fs.js` / `zip-fs.min.js`: Full `ZipWriter` / `ZipReader` plus virtual file system (`fs`), with embedded Web Worker code and WASM.
+- `zip-core.js` / `zip-core.min.js`: Minimal `ZipWriter` / `ZipReader`.
+- `zip-fs-core.js` / `zip-fs-core.min.js`: Minimal `ZipWriter` / `ZipReader` plus virtual file system (`fs`).
+
+Online builder:
+
+Alternatively, you can build your own version of zip.js with the online builder, see https://gildas-lormeau.github.io/zip.js/builder.
+
+Notes:
+- Files suffixed with `-native` rely on a pure JavaScript implementation of Compression Streams instead of a WASM module.
+- `zip-legacy.min.js` is the equivalent of `zip.min.js` before the version `2.8`, it relies on a JavaScript implementation of Compression Streams (if used) but only in web workers. Alternatively `zip-native.min.js` includes the Compression Streams implementation in the main environment and the web workers.
