Added ImageMagick-heic package to both Dockerfile and Dockerfile.fpm.
This is a separate EPEL subpackage that provides HEIC, HEIF, and AVIF
format support via libheif. Without it, ImageMagick is installed but
cannot process iPhone photos and modern image formats.
Also fixed MariaDB repo URL: AlmaLinux 10 uses $releasever=10 but
MariaDB mirrors don't have an 'almalinux10' directory. Changed to
'rhel10' which is the supported path for EL10 derivatives.

Reverts from ProxyPassMatch back to SetHandler + ProxyFCGISetEnvIf.
ProxyPassMatch couldn't override DOCUMENT_ROOT (Apache sets it as a
CGI param after all directives run). SetHandler with unconditional
ProxyFCGISetEnvIf correctly overrides both:
- DOCUMENT_ROOT: set to /home/{user}/public_html (FPM path)
- SCRIPT_FILENAME: constructed from DOCUMENT_ROOT + SCRIPT_NAME
This fixes WordFence WAF and other plugins that use DOCUMENT_ROOT to
locate config/log files. Tested on live sites with WordPress pretty
URLs, wp-admin, static assets, and WordFence WAF optimization.

SetHandler + ProxyFCGISetEnvIf doesn't work for path remapping because
reqenv('SCRIPT_FILENAME') is empty when the directive evaluates with
the SetHandler approach.
ProxyPassMatch directly maps .php URLs to the FPM container's filesystem
path, bypassing the SCRIPT_FILENAME rewrite issue entirely:
^/(.*\.php(/.*)?)$ -> fcgi://fpm:9000/home/{user}/public_html/$1
Static assets (CSS, JS, images) bypass the proxy since they don't match
\.php and are served directly by Apache from the read-only mount.
Tested and confirmed working on live site with WordPress (including
pretty URLs via .htaccess mod_rewrite).

The previous expr= with s|...|...| substitution syntax doesn't exist
in Apache expressions — it silently failed, leaving SCRIPT_FILENAME
pointing to /mnt/users/ which PHP-FPM can't find.
Fixed to use regex match in the conditional with backreferences:
reqenv('SCRIPT_FILENAME') =~ m#^/mnt/users/([^/]+)/([^/]+)/public_html(.*)#
-> /home/$1/public_html$3
This is also generic (captures user from the path) so the template
no longer needs per-user placeholder substitution for this directive.

The shared httpd serves files from /mnt/users/{user}/{domain}/public_html
but PHP-FPM containers have them at /home/{user}/public_html. When Apache
proxied PHP requests via fcgi, SCRIPT_FILENAME pointed to the Apache path
which doesn't exist inside the FPM container, causing "File not found".
Added ProxyFCGISetEnvIf to rewrite SCRIPT_FILENAME from the shared httpd
path to the FPM container path before proxying the request.

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.

- 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
