Fix production data fetching with static JSON

- Add build-time data fetching from Confluence
- Create build-data.js script to fetch and save data at build time
- Update App.tsx to use static JSON in production, API in development
- Install tsx for running TypeScript build scripts
- Configure Amplify to fetch data during build process
- Add public directory configuration to Vite

This fixes the white page error by providing data at build time instead of runtime.
