Enhance FrankenPHP configuration for performance and caching

- Updated Dockerfile to include additional PHP environment variables for OPcache and FrankenPHP threading configurations.
- Modified Caddyfile to improve encoding settings with minimum length and content type matching, and added precompression for static file serving.
- Adjusted worker configuration files to utilize new threading parameters for better resource management.
