fix(ui): Add triangular meshes and line support [FLOW-DEV-18]

[billcookie]

Overview

This PR adds Cesium rendering support for a new FlowGeometry3D geometry type that includes triangular meshes and line segments. It creates a new utility for converting FlowGeometry3D features into Cesium Primitives, a new React component to manage their lifecycle, and integrates triangular mesh support into the existing CityGML rendering pipeline.

What I've done

• New flowGeometry3DToPrimitives.ts utility and FlowGeometry3DData.tsx component to handle FlowGeometry3D features with triangular meshes and line segments as batched Cesium Primitives.
• Extended cityGmlGeometryToPrimitives.ts and CityGmlData.tsx to support triangularMesh geometry within CityGML features (for both known 3D types and unknown types), including a new meshPrimitive draw call.
• Fixed dataSources iteration in hooks.ts to use indexed access (.get(i)) instead of for...of, which is required by CesiumJS's DataSourceCollection API.
