fix: remove PUID/PGID env vars from ZNC container

LinuxServer s6-overlay requires starting as root to fix directory
permissions (/run, etc.) before dropping privileges. Setting PUID/PGID
forces immediate UID 1000 start, causing permission errors:
"fatal: /run belongs to uid 0 instead of 1000"

Let the container run as root with existing Polaris exemptions.
The s6-overlay init system handles privilege management internally.

Fixes CrashLoopBackOff in znc-0 pod.
