Fix Amplify environment variable access

- Simplified amplify.yml to export env var during build
- Updated both gallery and dadvocate pages to check multiple env var names
- Added debugging to show available env vars
- Added publicRuntimeConfig and serverRuntimeConfig to next.config.ts
- Created config helper in lib/config.ts
