- CPScripts/ensure_ftp_users_quota_columns.py checks information_schema and
ALTER TABLE users ADD COLUMN for custom_quota_enabled and custom_quota_size
when missing (fixes MySQL 1054 on FTP account creation).
- deploy-ftp-users-custom-quota-columns.sh copies script to CyberCP and runs
repair; restarts lscpd when active.
- upgrade_modules/10_post_tweak.sh runs the repair after upgrade sync.
