Add debug endpoint and environment variable configuration for development testing

- Introduced a new debug endpoint to validate environment variables, accessible only in development or when explicitly enabled.
- Updated the Next.js configuration to include the ENABLE_DEBUG_ENDPOINTS variable.
- Added a temporary environment variable for enabling debug endpoints in the Fargate service configuration.
