Separate Apache and PHP-FPM into distinct container roles to reduce
per-customer memory overhead on shared servers. Adds three new images:
- Dockerfile.fpm: PHP-FPM only (no Apache), listens on TCP port 9000
- Dockerfile.shared-httpd: Apache only (no PHP), with SSL and proxy_fcgi
- Existing Dockerfile unchanged for standalone mode
Key changes:
- detect-memory.sh: CONTAINER_ROLE env var (combined/fpm_only/httpd_only)
controls the memory budget split
- create-php-config.sh: FPM_LISTEN env var for TCP port vs Unix socket,
added /fpm-ping and /fpm-status health endpoints
- New entrypoints for each container role
- tune-mpm.sh for hot-adjusting Apache MPM settings
- shared-vhost-template.tpl with proxy_fcgi and SSL on port 443
- CI/CD builds all three image types in parallel

Switch PHP-FPM from pm=dynamic to pm=ondemand (zero idle workers),
auto-detect container memory via cgroups to calculate appropriate
limits, and generate Apache MPM config at runtime. All tuning values
are now overridable via environment variables.

PHP error logs were incorrectly being written to /etc/httpd/logs/error_log
instead of the expected /home/$user/logs/php-fpm/ directory. Updated the
php_admin_value[error_log] setting to point to the proper location.

- Apache mpm_event: Reduced StartServers from 10 to 2, adjusted spare threads
and worker limits for container environments
- PHP-FPM: Switched from static to dynamic process management with lower
process counts (5 max children instead of 10)
- Removed php-ioncube-loader from PHP 8.0 installation
- Expected memory reduction: 60-70% in idle state while maintaining responsiveness
