New KnoeUsersScreenMixin screen (knoe_users) appears in the install wizard
immediately after Kerberos Authentication (when kerberos is enabled).
- Runs etc/init_knoe_users.sh initialize in a background thread with live
console output, forwarding SERVICE_NAMESPACE/KNOE_KDC_NAMESPACE from the
installer state so the script always targets the right namespace
- Optional Gitea and GitLab admin token fields for service admin promotion
- Next button is disabled until provisioning succeeds (idempotent: button
re-enables on failure so the user can fix and retry)
- Nav chain: kerberos_config -> knoe_users -> argocd_config
Prev from argocd_config respects kerberos_enabled to route correctly
- Records STATUS in prole.cfg under [Knoe User Accounts] section
