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

// Scale to consider the radii. We could also do this once on the CPU when using the BoxGeometry,
// but doing it here allows us to change the radii without rewriting the vertex data, and
// allows all ellipsoids to reuse the same vertex data.

// With multi-frustum, when the ellipsoid primitive is positioned on the intersection of two frustums
// and close to terrain, the terrain (writes depth) in the closest frustum can overwrite part of the
// ellipsoid (does not write depth) that was rendered in the farther frustum.
//
// Here, we clamp the depth in the vertex shader to avoid being overwritten; however, this creates
// artifacts since some fragments can be alpha blended twice. This is solved by only rendering
// the ellipsoid in the closest frustum to the viewer.
