Subject: [PATCH] Fix local network access prompts in multi-site analysis

Replace hardcoded http://localhost:5001 fallback with relative /api paths
in useSimulationStore.js. The scan/start fetch and task_status SSE
connection were bypassing the Nginx/Vite proxy, causing browsers to
trigger Private Network Access prompts.
