Rebuild on the official PHP image instead of Sury's repo on bare Debian.
Fixes surfaced along the way: missing pkg-config/libonig-dev broke the
zip/mbstring extension builds, purging libzip-dev also auto-removed the
libzip5 runtime lib the compiled zip.so needs, phpredis needed bumping to
6.3.0 for PHP 8.5 header compatibility, and the php-fpm.conf listen
directive sed didn't match the commented-out default line so FPM never
created its unix socket, causing 503s from Apache's proxy_fcgi handler.
