Stop FreshRSS + MBG WordPress until PHP is patched

CERT-EU 2026-018 (CVE-2026-109618, CVE-2026-109619, CVSS 9.2): possible
unauthenticated RCE in PHP 5 and later. Both are internet-facing and are
the only PHP workloads (FreshRSS on PHP 8.2.29, WordPress on 8.3.30), so
scale them to 0 until their images ship a fixed PHP. PVCs and the MariaDB
cluster stay as they are.
