Fix Docker container startup and API endpoint configuration

- Update Dockerfile to use inline CMD instead of external start.sh script to resolve execution issues with CRLF line endings
- Fix nginx fastcgi_pass configuration to use localhost:9000 for PHP-FPM communication
- Correct API endpoint paths in frontend from /src/api.php to /api.php to match nginx document root configuration
- Ensure Composer dependencies are properly installed with PHP 8.3 compatibility
