LiteSpeed CyberPanel vhost serves /static/ from public/static while
collectstatic writes to STATIC_ROOT. Merge after collectstatic and ensure
webmail assets so /webmail/ Angular loads. Hook install/upgrade staticContent,
deploy scripts, and upgrade.sh; fix Django --noinput flag; restore lscpd
ownership on public/static after chown root. SnappyMail: require index.php on
install and validate tree after unzip on upgrade.
