Subject: [PATCH] fix(ferretdb): force C.UTF-8 locale to silence apt/perl
 locale warnings

A fresh Debian template has not generated the Proxmox host locale that pct exec
forwards (e.g. fr_FR.UTF-8), so apt, perl and apt-listchanges warn on every run.
Export LC_ALL=C.UTF-8 / LANG=C.UTF-8 globally and forward them through pct exec
(base tooling, the piped installer, and the host-side upgrade).
