fix(examples): use correct default ports matching run-all.ts

Each server now defaults to its assigned port from run-all.ts:
- basic-server-react: 3101
- basic-server-vanillajs: 3102
- budget-allocator-server: 3103
- cohort-heatmap-server: 3104
- customer-segmentation-server: 3105
- scenario-modeler-server: 3106
- system-monitor-server: 3107
- threejs-server: 3108
- wiki-explorer-server: 3109
