bot_dev1 85df71fc28 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

🚧 开发者: bot_dev1
